How to convert hours to minutes
One hour contains 60 minutes, so to convert hours to minutes you simply multiply by 60. For example, 3 hours × 60 = 180 minutes. Half an hour is 30 minutes, and 2.5 hours is 150 minutes.
Decimals are where mistakes creep in, because a decimal hour is not the same as hours and minutes written with a colon. 0.5 h is 30 minutes, 0.25 h is 15, 0.75 h is 45, and 0.1 h is 6 minutes rather than 10.
Working the other way round? The minutes to hours calculator handles that direction.
How to use this calculator
Enter a number of hours (whole or decimal) and the minutes appear instantly. To go the other way, use the seconds to hours calculator, or convert smaller units with the minutes to seconds calculator.
Timesheets and billing are the usual reason for the conversion. Payroll systems store a shift as 7.4 hours, a paper log records it as 7:24, and both mean 7 hours 24 minutes — or 444 minutes once you multiply by 60, which is the form most scheduling tools want.
Quick reference
1 hour = 60 minutes, 2 hours = 120 minutes, 5 hours = 300 minutes, 8 hours = 480 minutes, and 24 hours = 1,440 minutes. Decimal hours work too: 1.5 hours = 90 minutes.
Longer spans follow the same rule: a 12 hour shift is 720 minutes, a 40 hour working week is 2,400 minutes, and a full seven-day week of 168 hours is 10,080 minutes.
