Decimal hours for payroll

Payroll and billing systems often use decimal hours: 7 hours 45 minutes is 7.75 hours, not 7.45. To convert, divide the minutes by 60 (and seconds by 3,600) and add them to the hours. Going the other way, take the decimal part × 60 for minutes: 1.3333 hours is 1 hour 20 minutes. Common values: 15 minutes = 0.25, 30 minutes = 0.5, 45 minutes = 0.75, 6 minutes = 0.1.
