Time to Decimal Calculator

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

To convert time to decimal hours, divide the minutes by 60 and add them to the hours. 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours. 15 minutes = 0.25, 30 minutes = 0.5, 45 minutes = 0.75.

How to convert time to decimal hours

Divide the minutes by 60 and add the result to the whole hours. For seconds, divide by 3,600.

Decimal hours = hours + (minutes ÷ 60) + (seconds ÷ 3,600)

To go the other way, multiply the decimal part by 60. 6.4 hours is 6 hours plus 0.4 × 60 = 24 minutes.

A common mistake is treating 7:30 as 7.30. It is 7.5 hours, because 30 minutes is half an hour. At $20 an hour that error costs $4 per timesheet line.

Questions, answered

Things people actually ask.

Divide the minutes by 60. 15 minutes is 0.25 hours, 30 minutes is 0.5, 45 minutes is 0.75 and 20 minutes is 0.333.
7.75 hours. 45 ÷ 60 = 0.75, added to the 7 whole hours.
Pay is hours × rate, and you can only multiply a rate by a decimal number. 7:30 has to become 7.5 before it can be multiplied by an hourly wage.
Most payroll systems use two decimal places (hundredths of an hour). Some use quarter-hour rounding, which is allowed under FLSA rules only if it averages out and does not consistently favor the employer.
Multiply the decimal part by 60. 8.6 hours is 8 hours plus 0.6 × 60 = 36 minutes, so 8:36.
