Convert decimal minutes to Excel time

Excel formula: Convert decimal minutes to Excel time
Generic formula 

To convert minutes in decimal format to a proper Excel time, divide by 1440. In the example shown, the formula in C6 is:


Because B6 contains 60 (representing 360 minutes) the result is 60/1440 = 0.04167, since 60 minutes = 1 hour = 1/24 day. Cell D6 shows the same result formatted as time, which displays 1:00.


In the Excel date system, one day is equal to 1, so you can think of time as fractional values of 1, as shown in the table below:

Hours Fraction Minutes Value Time
1 1/24 60 0.04167 1:00
3 3/24 180 0.125 3:00
6 6/24 360 0.25 6:00
4 4/24 240 0.167 4:00
8 8/24 480 0.333 8:00
12 12/24 720 0.5 12:00
18 18/24 1080 0.75 18:00
21 21/24 1260 0.875 21:00

This means if you have a decimal number for minutes, you can divide by 1440 (24 x 60) to get the correct representation of minutes in Excel. After dividing by 1440, you can apply a time format of your choice, or use the result in a math operation with other dates or times.

In the example, since B11 contains 720 (representing 720 minutes) the result is 720/1440 = 0.5. Once a time format like h:mm has been applied, Excel will display 12:00.


To display hours that represent a duration longer than 24 hours, or minutes in durations longer than 60 minutes, you'll need to adjust the number format by adding square brackets.

[h]:mm // hours > 24
[m]  // minutes > 60

The brackets signal to Excel that the time is a duration, and not a time of day.
