How do you convert time to decimal hours?

To convert a time to decimal hours, divide the minutes by 60 and add the whole hours. That makes 15 minutes 0.25 hours, 30 minutes 0.50, and 45 minutes 0.75, so 7:45 is 7.75 hours. Payroll usually rounds to two decimal places. Pay is most accurate when it is calculated from the minutes, not the rounded decimal.

How it works

  1. Hours stay the same. Only the minutes change. In 7:45, the 7 stays 7.
  2. Divide the minutes by 60. 45 ÷ 60 = 0.75.
  3. Round to two decimal places. 7 + 0.75 = 7.75 hours.
  4. To go back, multiply the decimal part by 60. 7.40 hours is 0.40 × 60 = 24 minutes, so 7 hours 24 minutes, not 7:40.

Worked example: why pay comes from minutes

Someone works 7 hours 50 minutes at $19.00 an hour.

  • 50 ÷ 60 = 0.8333…, which rounds to 0.83. The decimal is 7.83 hours.
  • Pay from minutes: 470 minutes × $19.00 ÷ 60 = $148.83
  • Pay from the rounded decimal: 7.83 × $19.00 = $148.77

The 6-cent gap comes from rounding before multiplying. Over a year of shifts it adds up, which is why this calculator works out pay from minutes and uses decimals only for display.

Frequently asked questions

How do I convert minutes to decimal hours?

Divide the minutes by 60 and round to two decimal places. 20 minutes is 20 ÷ 60 = 0.33 hours. Add the result to the whole hours, so 8 hours 20 minutes is 8.33 hours.

Is 7:30 the same as 7.3 hours?

No. 7:30 is 7 hours 30 minutes, which is 7.50 hours. 7.3 hours is 7 hours 18 minutes. Mixing the two up is one of the most common timesheet mistakes.

How do I convert decimal hours back to minutes?

Multiply the decimal part by 60. 6.25 hours is 6 hours plus 0.25 × 60 = 15 minutes, so 6:15. For 6.8 hours, 0.8 × 60 = 48 minutes, so 6:48.

What is 0.1 hours in minutes?

6 minutes. That is why some employers round to the nearest tenth of an hour: each tenth is exactly 6 minutes. 0.5 hours is 30 minutes, and 0.25 hours is 15 minutes.

How many decimal places should payroll use?

Two places is the usual standard and gives an error of less than a minute. Some systems use tenths of an hour, which is the same as rounding to 6 minutes. Whatever your payroll uses, pay is most accurate when it is calculated from the total minutes.

Why is my pay slightly different from hours × rate?

Usually because the hours were rounded before multiplying. 7.83 × $19.00 = $148.77, but 7 hours 50 minutes at $19.00 is $148.83. The gap is small for one day but grows over a pay period.
