How the Time Converter works

To convert decimal hours to hours and minutes, keep the whole number as the hours and multiply the decimal part by 60 for the minutes. If that leaves a decimal, multiply its decimal part by 60 again for the seconds.

For 7.65 hours: 7 hours, and 0.65 × 60 = 39 minutes, so 7:39. For 2.758 hours: 2 hours, 0.758 × 60 = 45.48 minutes, and 0.48 × 60 = 28.8 seconds, so 2:45:28.8, or 2 hours 45 minutes to the nearest minute.

The digits after the point are tenths and hundredths of an hour, so 7.5 hours is 7 hours 30 minutes and 7.65 is 7 hours 39. Reading 7.65 as 7 hours 65 minutes, or as 7:65, is the mistake to avoid.

The same method works for other units. 4.25 minutes is 4 minutes and 0.25 × 60 = 15 seconds. 1.75 days is 1 day and 0.75 × 24 = 18 hours.

Timesheet and payroll software often exports hours as decimals. The common ones are 0.1 hour = 6 minutes, 0.25 = 15, 0.5 = 30, 0.75 = 45 and 0.9 = 54.
