*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 ).

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:

`=INT(A2*24)`

#### 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):

`=A2*1440`

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

`=INT(A2*1440)`

You can view the results in the screenshot below:

#### 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):

`=A2*86400`

#### 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)`

Tips:

- If any of the above formulas returns a value formatted as time, simply change the cell's format to
**General**to display it as a number. - 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:

`=INT(A2)`

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

`=A2-B2`

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:

`=MOD(A2,1)`

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.

The formula to enter in cell D4 is as follows:

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

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!

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("6:20 PM")`

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

`=TIMEVALUE(A2)`

where A2 contains a text string

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:

`=TEXT($A2,"h:mm:ss")`

The screenshot below demonstrates other possible formats:

## 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.

- Divide the numbers by 24 (there are 24 hours in a day). The formula can be as simple as =A2/24.
- 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 format time in Excel for more details.

If your time exceeds 24 hours, 60 minutes, 60 seconds, use these guidelines to correctly show it.

That's all for today. If someone wants to get the first-hand experience with the formulas discussed in this article, you are most welcome to download the sample workbook below.

Hello!

I was recently working with a client's required Timesheet. He asked me to add columns to enter time that should be easy for workers. I decided to add two columns and a hidden for the resulted one in format of [h]:mm. The two columns for hrs and mins separately. Then I was to convert the result in AM/PM.

Like, when a worker puts In-Time for 7:00 AM as 7 in one column and 0 in other. But for the Break-Time at 12:00 PM he inputs 12 and 0, and for Restart-Time at 12:30 PM he puts 12 and 30 in the two columns, and then finally Finish-Time for 6:30 PM like 6 and 30 (instead of 18 and 30).

Now I have to add them to the Total hrs they worked. Is there any formula for this to work, please.

Regards

Hi! To convert two numbers to hours and minutes, use the TIME function. But you cannot automatically convert 6 to 6 PM or 1 to 1 PM. So you need to write the hours in 24 hour format.

How do you convert the below text into an average

1week, 2days, 3hour, 12minutes

1week, 3days, 2hours, 40minutes

And so on

Hi! Split text into cells using these instructions: How to split text string in Excel by comma, space, character or mask. Or you can use the TEXTSPLIT function. For more information, click here: TEXTSPLIT function in Excel: split text strings by delimiter. Then extract numbers from each cell as described here: How to extract number from string in Excel.

Perform the operations with these numbers that you need but that are not clear from your question.

I have a time tracking spreadsheet in excel.

Each row is an activity with a start time and duration

I want to enter whole numbers like 20, 30, 45, 90 for my duration and have excel convert the whole number to h:mm and add it to f22 to be f21

For instance; F22 is my starting time for the day, lets say 8:00, it is formatted as hh:mm

G22 is my duration - currently I must add as 0:20 for 20 minutes and the next start time in F21 is calculated by excel

If I can enter the duration as a whole number, it would save me keystrokes

Hi! If you want to enter minutes as a number instead of time, you can use these instructions to convert that number to time for calculating time: Convert number to time format. Based on your information, the formula might look something like this:

=F22+G22/1440

Thanking you

Hi! You can extract the last word from a text string using these instructions: Excel: how to extract first and last word from cell. Replace "." with ":" using the SUBSTITUTE function. Convert this text to time using the TIMEVALUE function and the recommendations from the article above. Here is an example formula:

=TIMEVALUE(SUBSTITUTE(TRIM(RIGHT(SUBSTITUTE(A2," ",REPT(" ",LEN(A2))),LEN(A2))),".",":"))

Thanks a lot Sir, it is working very well.

If found any problem i will inform you Sir....

Sir, Thanks a lot for your help,

I tried myself but not succeed.

Can you change only one time for me for my help please.

4 hr. 17 min.10sec.

Hi! What formula did you use? Is this time written as text or as time? If this text, extract all numbers from the text.

The following tutorial should help: How to extract number from string in Excel

Convert these numbers to time using the TIMEVALUE function.

=TIMEVALUE(SUBSTITUTE(TRIM(CONCAT(IF(ISNUMBER(--MID(H1,ROW($1:$95),1)),MID(H1,ROW($1:$95),1)," ")))," ",":"))

Set the time format you want in the formula cell. Or convert that time to minutes as described in the article above.

If this does not help, explain the problem in detail.

I want to convert this time format into minutes pl, I will be very thankful to you...

13 hr. 59 min.15sec.

Hi! Pay attention to the following paragraph of the article above: How to convert time to minutes in Excel. If this is not what you wanted, please describe the problem in more detail.

Thank you Sir for your reply.

I have a file where is the time is in the format like this format:-

4 hr. 17 min.10sec.

3 hr. 50 min.25sec.

1 hr. 59 min.20sec.

2 hr. 40 min.40sec.

4 hr. 20 min.25sec.

2 hr. 16 min.15sec.

I want to convert into minutes like 150, 140 as please help me.

Hi! I have already answered this question for you. If this is not what you need, please explain why and explain the problem in more detail.

I have a time in excel cell as 03:15 and i want to display in another cell as 3 hours and 15 minutes. How i can convert this. Kindly guide.

Hi! If I understand your task correctly, try to use custom time format:

h "hours and "mm "minutes"

How do I convert text in a cell as 84h 30m into 84.25 as numerical figure? Thank you.

Hi! Extract numbers from the text. Look for the example formulas here: Excel substring functions to extract text from cell. Then combine them using the & operator. For example:

LEFT(A1,2)&"."&MID(A1,5,2)

But I can't guess why you want to convert 30 minutes to 0.25 hours.
