How to convert hours to minutes
minutes = hours × 60
hours = minutes ÷ 60
decimal hours: minutes = 0.xx × 60
There are exactly 60 minutes in an hour, so you multiply hours by 60. The catch is decimals: 2.5 hours is 2 hours 30 minutes, not 2 hours 50 minutes. To convert the part after the decimal point, multiply it by 60, so 0.75 hours is 45 minutes. The calculator shows both forms.

Decimal hours on timesheets
Payroll and billing systems often record time in decimal hours, so 6 minutes is 0.1 hour and 15 minutes is 0.25 hour. To convert minutes to decimal hours, divide by 60: 20 minutes is 0.333 hours, which is why 20 minutes is often rounded to 0.33. A day has 1,440 minutes and a week has 10,080 minutes, so a 40-hour week is 2,400 minutes. For other durations, the unit converter includes days, weeks and years.
