## Summary

To convert a valid Excel time into decimal minutes, you can multiply by 1440. In the example shown, the formula in C6 is:

``````=B6*1440
``````

which returns a value of 30.

## Generic formula

``=A1*1440``

## Explanation

In the Excel time system, one 24-hour day is equal to 1. This means times and hours are fractional values of 1, as shown in the table below:

Hours Time Fraction Value
1 1:00 AM 1/24 0.04167
3 3:00 AM 3/24 0.125
6 6:00 AM 6/24 0.25
4 4:00 AM 4/24 0.167
8 8:00 AM 8/24 0.333
12 12:00 PM 12/24 0.5
18 6:00 PM 18/24 0.75
21 9:00 PM 21/24 0.875

Because each hour can be represented as 1/24, you can convert an Excel time into decimal hours by multiplying the value by 24, and convert to decimal minutes by multiplying the value by 1440 (24 * 60) . With the time value 6:00 cell A1, you can visualize the conversion like this:

``````=A1*(24*60)
=(6/24)*1440
=0.25*1440
=360
``````

The Excel time 6:00 converts to 360 minutes.

### Format result as number

When you multiply a time value by 1440, Excel may automatically format the result using a time format like h:mm, which will display the value incorrectly. To display the result as a regular number, apply the General or Number format. Author ### Dave Bruns
