Hours to Decimal Calculator

Convert hours and minutes into decimal hours for timesheets and payroll, or turn decimal hours back into hours, minutes and seconds.

How to convert hours and minutes to decimal

Decimal hours = hours + minutes ÷ 60

Divide the minutes by 60 and add the result to the whole hours. For example, 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours.

Minutes = decimal part × 60

Keep the whole number as hours and multiply the decimal part by 60. For example, 8.6 hours is 8 hours and 0.6 × 60 = 36 minutes, or 8 h 36 min.
