To convert a valid Excel time into decimal hours, simply multiply by 24. In the example shown, the formula in C6 is:
which returns a value of 1.
How this formula works
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:
Because each hour can be represented as 1/24, you can convert an Excel time into decimal hours by multiplying the value by 24. For example, with the time value 6:00 cell A1, you can visualize the conversion like this:
Format result as number
When you multiply a time value by 24, 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.
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. How this formula works In the Excel time system, one 24-hour day is equal to 1. This...
To convert hours in decimal format to a value Excel recognizes as time, divide by 24. In the example shown the formula in C5 is: = B5 / 24 which returns 0.04167, the equivalent of 1 hours. Cell D6 shows the same result formatted as time, which...
To convert minutes in decimal format to a proper Excel time, divide by 1440. In the example shown, the formula in C6 is: = B6 / 1440 Because B6 contains 60 (representing 360 minutes) the result is 60/1440 = 0.04167, since 60 minutes = 1 hour = 1/24...
