How to convert minutes to decimal hours
A decimal hour is just the fraction of an hour your minutes represent. Since 1 hour = 60 minutes, divide the minutes by 60:
decimal hours = minutes ÷ 60
If you logged a time like 1 hour 15 minutes, add them together: 1 + (15 ÷ 60) = 1.25 decimal hours. The converter above handles the hours and minutes together, and also reverses the math if you start from a decimal.
