How it works
To go from decimal hours to hours and minutes, the whole part is the hours, and the fraction multiplied by 60 is the minutes.
To go back, divide the minutes by 60 and add the result to the hours. Forty-five minutes is 0.75 of an hour.
Worked example
7.75 decimal hours is 7 h 45 min. In the other direction, 7 hours and 45 minutes is 7.75 decimal hours.
Questions
Why use decimal hours at all?
A decimal fits into a simple multiplication, such as rate times hours, so it is common on pay sheets.
Should I round the decimal?
Round only at the end. Rounding each step can shift the total by a few minutes.
Does the hours and minutes view show seconds?
Yes. It shows seconds too, which are zero when the decimal converts exactly.
