Why payroll uses decimal hours

Payroll and billing systems multiply hours by an hourly rate, which only works with decimal numbers. To convert minutes to a decimal, divide by 60: 15 minutes is 0.25 hours, 30 minutes is 0.5 and 45 minutes is 0.75. So 7 hours 45 minutes is 7.75 hours.

To go the other way, multiply the decimal part by 60: 8.4 hours is 8 hours and 0.4 × 60 = 24 minutes.
