Decimal Hours to Hours and Minutes

Multiply the leftover by 60

A payroll decimal has a whole-hour part and a fraction. The whole hours stay hours. Minutes = the fraction × 60, rounded to the nearest minute. For 8.75 the whole hours are 8 and the fraction is 0.75. Three quarters of 60 is 45, so the clock time is 8:45. For 8.50 the fraction is one half and the minutes are 30. For 0.10 the whole hours are 0 and the minutes are 6. That last one surprises people who expect a tenth of an hour to be ten minutes. A tenth of sixty is six.

Rounding is the only delicate step. The display multiplies the fraction by 60 and rounds to the nearest minute. If the rounded minutes land on 60, they carry into the next hour and the minutes become 0. You will not see “8 hours 60 minutes.” You will see 9 hours and 0 minutes. The same rule is written on assumptions and formulas. Two decimal places are the default. If you type more precision, the minutes still come back as a whole number, because a clock does not display 0.4 of a minute in this converter.

Reading a timesheet that is already decimal

Software often stores the week as decimals and prints the pay from those decimals. A person still wants the clock time, to compare the line with a punch. 7.25 is 7 hours and 15 minutes. 7.33 is about 7 hours and 20 minutes, because 0.33 × 60 is 19.8, which rounds to 20. 7.3333 is closer to the same 20 minutes. If you need the minutes to match a quarter-hour chart exactly, start from the quarter, not from a rounded hundredth. The hours to decimal chart lists 0:00 through 12:00 in 15-minute steps, and minutes 0 through 59 on their own.

Going the other way, hours and minutes into a decimal, is hours and minutes to decimal. Both directions also live on the hours to decimal calculator. After the hours are a number you can multiply, a workweek goes to the overtime calculator. Hours that are already past 40, priced at 1.5 times, go to the time and a half calculator. This page does not decide overtime. It only turns the fraction back into minutes.

What you can paste

The decimal field accepts 8.75, 8.5, and 8.50. The paste box accepts those decimals too. If you paste a colon, such as 8:45, the form treats it as clock time and fills the hours and minutes instead. That is the forward conversion, and it is there so a mixed timesheet does not need a second tool. Negative decimals are rejected. The calculation runs in the browser and nothing is uploaded. Payroll context for tenths and hundredths is on hours to decimal payroll.
