How to convert time to decimal number, hours, minutes or seconds in Excel

The tutorial demonstrates different ways to convert time to decimal in Excel. You will find a variety of formulas to change time to hours, minutes or seconds as well as convert text to time and vice versa.

Because Microsoft Excel uses a numeric system to store times, you can easily turn hours, minutes and seconds into numbers that you can use in other calculations.

In general, there are two ways to convert time to decimal in Excel - by changing the cell format and by using arithmetic calculations or Excel time functions, such as HOUR, MINUTE and SECOND. Further on in this tutorial, you will find the detailed explanation of the first way and formula examples demonstrating the other technique.

How to convert time to decimal number in Excel

Overall, there are three ways to change a time value to a decimal number: arithmetic operation, CONVERT function or a combination of three different Time functions.

The easiest way to convert time to decimal in Excel is to multiply the original time value by the number of hours, seconds or minutes in a day:

  • To convert time to a number of hours, multiply the time by 24, which is the number of hours in a day.
  • To convert time to minutes, multiply the time by 1440, which is the number of minutes in a day (24*60).
  • To convert time to seconds, multiply the time time by 86400, which is the number of seconds in a day (24*60*60 ).

Convert time to a decimal number in Excel

In the following sections, you will learn the other methods of converting times to a decimal number in Excel.

How to convert time to hours in Excel

This section demonstrates 3 different formulas to convert hours from the standard time format (hh:mm:ss) to a decimal number.

Formula 1: Arithmetic calculation

You already know the fastest way to convert a time value to a number of hours in Excel - multiplying by 24, i.e. by the number of hours in one day:

=A2*24 (where A2 is the time value)

To get the number of compete hours, embed the above formula in the INT function that will get rid of the fractional part:


The formula and arithmetic calculation to convert time to hours in Excel

Formula 2: CONVERT function

Another way to perform the "time > hours" conversion is to use the following Convert formula:

=CONVERT(A2, "day", "hr")

Formula 3: HOUR, MINUTE and SECOND functions

Finally, you can use a bit more complex formula, whose logic, however, is quite obvious. Extract the individual time units by using the HOUR, MINUTE and SECOND functions, then divide minutes by 60 (the number of minutes in an hour) and seconds by 3600 (the number of seconds in an hour), and add up the results:

=HOUR(A2) + MINUTE(A2)/60 + SECOND(A2)/3600

How to convert time to minutes in Excel

The same three methods can be used to convert minutes from the standard time format to a decimal number.

Formula 1: Arithmetic calculation

To convert time to total minutes, you multiply time by 1440, which is the number of minutes in one day (24 hours * 60 minutes = 1440):


If you want to return the number of compete minutes, utilize the INT function like in the previous example:


You can view the results in the screenshot below:
Converting time to minutes in Excel

Formula 2: CONVERT function

To do the "time > minutes" conversion with the CONVERT(number, from_unit, to_unit) function, supply "day" as the unit to convert from and "mn" as the unit to convert to:

=CONVERT(A2, "day", "mn")

Formula 3: HOUR, MINUTE and SECOND functions

One more way to get the number of minutes is to multiply hours by 60 and divide seconds by the same number:

=HOUR(A2)*60 + MINUTE(A2) + SECOND(A2)/60

How to convert time to seconds in Excel

Converting time to total seconds in Excel can be done in a similar fashion.

Formula 1: Arithmetic calculation

Multiply the time value by 86400, which is the number of seconds in a day (24 hours * 60 minutes * 60 seconds = 86400):

Converting time to seconds in Excel

Formula 2: CONVERT function

The formula is basically the same as in the above examples with the only difference that you convert the "day" unit to "sec":

=CONVERT(A2, "day", "sec")

Formula 3: HOUR, MINUTE and SECOND functions

Use the HOUR, MINUTE and SECOND functions like in the two previous examples (I believe at this point you don't need any further explanation of the formula's logic :)

=HOUR(A2)*3600 + MINUTE(A2)*60 + SECOND(A2)


  1. If any of the above formulas returns a value formatted as time, simply change the cell's format to Generalto display it as a number.
  2. To convert time to a decimal number that represents the time in the internal Excel system, apply the General format to the cell. With this approach, 23:59:59 will be converted to 0.99999, 06:00 AM to 0.25, and 12:00 PM to 0.5. If an integer part of the converted number is greater than zero, it means that your cell contains both date and time values.

How to split date and time in Excel

As is often the case, your Excel worksheet may contain dates and times in one cell, while you want to split them into two separate cells.

Remembering that in the internal Excel system the date value is stored as a whole part and the time value as a fractional part of a decimal number, you can extract the date using the INT function, which rounds the cell value down to the nearest integer.

Supposing your original dates and times are in column A, the following formula will accomplish the separation:

Use the INT function to extract the date values

To extract the time portion, subtract the date returned by the above formula from the original date and time value:


Where column A contains the original date & time values and column B contains the dates returned by the INT function.

If you'd rather not have time values linked to the separated dates (for example, you may want to remove the date column in the future), you can use the following MOD formula that refers to the original data only:

Splitting date and time in Excel

Tip. If the separated date and time values are not displayed properly, change the format of the new columns to Date and Time, respectively.

This is how you split date and time in Excel. If you want to further separate hours, minutes and seconds into individual columns, then use the HOUR, MINUTE and SECOND functions, as demonstrated in How to get hours, minutes and seconds from a timestamp.

How to spell time in Excel

Sometimes, you may need to convert time into the format that reads something like "# days, # hours, # minutes and # seconds". A good thing is that you already know all the ingredients of the formula:

  • Extract days using the INT function;
  • Extract time units with HOUR, MINUTE and SECOND functions, and
  • Concatenate all parts in a single formula.

Having difficulties with figuring out a proper formula for your worksheet? The following example will make things easy!

Supposing you have the dates of upcoming events in column B beginning in cell B4, and the current date and time returned by the NOW() function in cell B1.

The formula to calculate the time difference is as simple as =B4-$B$1. Of course, nothing prevents you from subtracting the current date and time directly with =B4-NOW().

And now, let's make a countdown timer that would show how many days, hours, minutes and seconds are left until each event.
Setting up a countdown timer in Excel

The formula to enter in cell D4 is as follows:

=INT(C4) & " days, " & HOUR(C4) & " hours, " & MINUTE(C4) & " minutes and " & SECOND(C4) & " seconds"
The formula to spell time in Excel

If you wish to get rid of 0 values, like in cells D6 and D7 in the screenshot above, then include the following IF statements:

=IF(INT(C4)>0, INT(C4)&" days, ","") & IF(HOUR(C4)>0, HOUR(C4) & " hours, ","") & IF(MINUTE(C4)>0, MINUTE(C4) & " minutes and ","") & IF(SECOND(C4)>0, SECOND(C4) & " seconds","")

All zeros are gone!
The formula to spell time in Excel excluding zero values

Note. When either of the above formulas refers to a negative number, the #NUM! error will appear. This may happen when you subtract a bigger time from a smaller one.

An alternative way to write time in words in Excel is to apply the following custom time format to the cell: d "day," h "hours," m "minutes and" s "seconds". No formulas and no calculations are required! For more information, please see Creating a custom time format in Excel.

Convert text to time in Excel

If your time formulas and calculations do not work right, time values formatted as text is often the cause. The fastest way to convert text to time in Excel is using the TIMEVALUE function.

The Excel TIMEVALUE function has just one argument:


Time_text is a text string in any of the time formats that Excel can recognize. For example:


=TIMEVALUE("6-Jan-2015 6:20 PM")

=TIMEVALUE(A2) where A2 contains a text string
Convert text to time using the Excel TIMEVALUE function

As you see, the formulas with cell references and corresponding text strings deliver identical results. Also, please notice the left alignment of time strings (text values) in cells A2 and A6 and right-aligned converted time values in column D.

Convert time to text in Excel

Supposing you have an Excel file full of times formatted to look like "8:30:00 AM" and you want to convert them to the text format. Simply changing the cell's format to TEXT won't work because this would change your time values to underlying numeric representation of the time. For example, 8:30:00 AM will be converted to decimal 0.354166666666667.

So, how do you convert cells to the text format so that your cells still have the time in them? The answer is to use the TEXT function that converts a numeric value to text with the display formatting that you specify, for example:


The screenshot below demonstrates other possible formats:
Converting time to text in Excel

How to convert numbers to time format in Excel

If you have a list of numbers such as 1, 2, 3.5 and you want to convert them to a time format, for example 1:00:00, 2:00:00 or 3:30 AM, perform the following steps.

  1. Divide the numbers by 24 (there are 24 hours in a day). The formula can be as simple as =A2/24.
  2. Select the cell(s) with the formula result, right-click and select Format Cells from the context menu or press Ctrl+1. Either way, the Format Cells dialog will appear, you select Time on the left pane under Category, and choose the format you want on the right pane under Type. Please see How to apply or change the time format in Excel for more details.

  2. Scott says:

    How do I return the second value from this number 00:00:24.306? When I use the Second(cell) all I get is 24. When I format the cell for 3 decimal places, I get 24.000. I would like to get 24.306.

    • Hi Scott,

      You can use the TEXT function, for example:
      =TEXT(A1, "ss.000")

      The result of the above formula is a text string. To convert it to a number, you can multiply the returned value by 1, and then format the cell for 3 decimal places:
      =1*TEXT(A1, "ss.000")

      • Joao says:

        I have a similar problem with pivot tables. I have formatted all cells with "mm:ss,000" , but when the pivot is updated to sum all time cells, it doesn't consider the decimals ...
        My use case is to sum all several time cells on a competition ... therefore decimals are important.
        Can you help ?

    Hi guys,

    Thanks for the solutions you've shared. I found them very helpful, though I am not that 100% sure that I can get them right. I haven't tried yet some of them, and to what my concern is, I didn't find a solution to my problem still despite of all this shared solutions. Could anyone just direct me to a certain solution to my case?

    My question was, how may I convert a given sample/answer (ex: 3days 10hours 35minutes) in a certain cell into a total minutes only (ex: 382719)?

    In other words I just want to simply convert them into total minutes using 1 formula with the given sample above as: 3days 10hours 35minutes

    Many thanks,


    • Hello, Adzhar,

      Please try the following formula for your task:
      =INT(LEFT(A2; FIND("day"; A2) - 1)) * 24 * 60 + INT(MID(A2; FIND(" "; A2) + 1; FIND("hour"; RIGHT(A2; LEN(A2) - FIND(" "; A2))) - 1)) * 60 + INT(MID(A2;FIND(" ";A2;FIND("hour";A2))+1;FIND("min";A2)-FIND(" ";A2;FIND("hour";A2)) - 1))

    Hello, this has helped a lot, I have been able to calculate work units into total hours, but now I want to convert total hours calculated, 466:56 - into FTE.

    Where 466:56 is the work units required to be worked in a month, and 168 hours is the amount of hours a staff member works a month so the FTE should be around 2.8

    Dividing the cell with (=F11/189) 466:56 by 189 in does not work as the number in the "=F11" is shown as 19.46.

    • Hello Lisa,

      To get it right and consider the AM/PM time, please use this formula:
      =LEFT(TEXT(A1,"h AM/PM"),LEN(TEXT(A1,"h AM/PM"))-3)&":"&IF(INT(MINUTE(A1)*1.66)<10," ","")&INT(MINUTE(A1)*1.66)&":"&TEXT(A1,"ss AM/PM")

      Where A1 is the cell with the original time.

      • LEFT(TEXT(A1,"h AM/PM"),LEN(TEXT(A1,"h AM/PM"))-3) gets the numeric symbols of time including AM/PM.
      • IF(INT(MINUTE(A1)*1.66)<10," ","")&INT(MINUTE(A1)*1.66) gets minutes with leading 0.
      • TEXT(A1,"ss AM/PM") gets seconds with leading 0 and AM/PM.

    dd:hh:mm:ss (days:hours:minutes:seconds)
    The second column shows how many tasks completed in that time (usually in the thousands).
    Is there a simple way to show how long is spent on each task?

  45. Kannan says:

    Hi All,
    I try to calculate total hours and minutes for below list of values.
    05:07:00 05:33:00 06:29:00 06:29:00 06:28:00 07:01:00
    (Those values are placed from B3 column the G3 column)
    I tried this formula
    =MINUTE (SUM (B3: G3) /60) &":"&SECOND (SUM (B3: G3) /60)
    Now I have got exact time, but there are some discrepancies in minutes.
    As per the formula I need to get "37:07:00", but I used to get "37:10:00".
    Kindly help some one to solve this issue.

    we have a daily reports and they are counted from 20:00 hours to 08:00 hours, I found a problem counting the hours,

    for example if work started at 23:00 and completed at 06:00 hours, what formula shall I use to get right result?

    xls. simply takes 23:00-06:00 = 17, which is not right,

    I found a way but I believe the is must be a easier way??

  51. alex says:

    I have data that is formatted in the following manner.

    "22 minutes" where the minutes are written as a number followed by the word "minutes" as well as "1 hr 30 min" where the time is larger than an hour and they are written with a number for the hour followed by "hr" and the a number for the minutes followed by "min".

  82. VIKASH says:


    I want to convert time (06:30) to number (0630) in excel.

    • Doug says:

      I think the simplest way to convert a value that is already formatted as time in Excel is to copy the values from Excel and paste them into Word as plain text.
      When they're in Word, replace the ":" with nothing, then copy these numbers and paste them into Excel.
      When they're in Excel, format the cells as Custom format "0000" and you'll see the values displayed as you need them.

    • Doug says:

      Have you tried to format the cell as a number?
      It sounds like it is formatted as something else.
      If formatting it as a number doesn't work try the custom format [H]:MM:SS

    • Doug says:

      I found this explanation and conversions on Excel Tips from John Walkenbach.
      If you import data you might encounter time values stored as Unix timestamps. Unix time is defined as the number of seconds since midnight (GMT time) on January 1, 1970 -- also known as the Unix epoch.

      For example, here's the Unix timestamp for August 4, 2008 at 10:19:08 pm (GMT):

      To create an Excel formula to convert a Unix timestamp to a readable data and time, start by converting the seconds to days. This formula assumes that the Unix timestamp is in cell A1:

      Then, you need to add the result to the date value for January 1, 1970. The modified formula is:

      Finally, you need to adjust the formula for the GMT offset. For example, if you're in New York the GMT offset is -5. Therefore, the final formula is:

      A simpler (but much less clear) formula that returns the same result is:

      Both of these formulas return a date/time serial number, so you need to apply a number format to make it readable as a date and time.

      I've found that the custom format m/d/yyyy hh:mm:ss works pretty well. Be sure to make your cell wide enough to accommodate the size of the value otherwise you'll get ##### displayed in the cell.
      I used the formula =DATE(1970,1,1)+A5/86400
      After I do all of this your number turns out to be 9/15/2017 11:36:58
      If you want just the 11:36:58 part you'll need to copy the 9/15/2017 11:36:58 and Paste Special/Values into another cell and copy the 11:36:58 into another cell. At this point it will be text, so if you want to do a DATEDIF or other calculation you'll need to use the first conversion for that.

      I would use the Text-to-Columns tool and in the third window select the date and the AM portions and click Don't Import option. Then format the data as Time in the Format Cells window.

    Thanks for the tutorial blog.

    I have a sheet wherein I will be calculating the time spent by my team member.

    Time-in will be enter in column B and time-out in column C, I will be calculating the total time spent in column D by formula =TEXT(c2-b2, "").

    I want to highlight the column D with one color, if the time spent is more than 9 hours and with another color, if the time spent is more than 10 hours.

    What formula should I use in Conditional Formatting? Or is there any other way of highlighting the column D cells based on their values.
