How to convert timesheet minutes to decimal hours

Updated November 14, 2026 · Worked examples use whole minutes

Divide the minutes by 60, then add the whole hours. For a shift lasting 7 hours 45 minutes, the fractional part is 45 ÷ 60 = 0.75. The result is 7.75 hours.

Calculate it step by step

Work out the shift duration after deducting any unpaid break. Keep the hours and minutes separate.
For a pay period, add all the worked minutes first. Divide the total by 60 and round the result to the number of decimal places you need.
To read a decimal back as a duration, multiply the part after the decimal point by 60. A value of 37.25 hours means 37 hours 15 minutes.

Worked example

A 9 am to 5:10 pm shift spans 8 hours 10 minutes. After a 35-minute unpaid break, 7 hours 35 minutes remain. That is 455 minutes ÷ 60, or 7.58 hours when shown to two decimal places.

Each 15 minutes is a quarter of an hour, so 45 minutes is 0.75 hours.

Values are rounded to two decimal places. Add the minutes across all shifts before converting the period total.

Which decimal-hour mistakes should you avoid?

Pay attention to the separator. In a duration such as 7:30, the 30 counts minutes. In a decimal such as 7.30, the fraction counts parts of an hour. Multiplying 0.30 by 60 gives 18 minutes, so those two entries differ by 12 minutes.

Start with whole minutes when adding several shifts. Some fractions repeat, so rounding each day before adding can move the displayed total by a hundredth. For example, three shifts of 7 hours 20 minutes each add up to exactly 22 hours. Adding three rounded values of 7.33 gives 21.99.

Quick answers

What is 8 hours 20 minutes as a decimal?

20 ÷ 60 = 0.333…, so 8 hours 20 minutes is 8.33 hours to two decimal places.

How do I convert decimal hours back to minutes?

Multiply the decimal part by 60. 6.4 hours is 6 hours plus 0.4 × 60 = 24 minutes, or 6 hours 24 minutes.
