Quick Answer: Converting Minutes to Decimal Hours
Decimal Hours = Whole Hours + (Minutes ÷ 60).
To convert minutes to decimal payroll hours, divide minutes by 60. For example: 7 hours and 45 minutes = 7 + (45 ÷ 60) = 7.75 decimal hours. To convert back to clock minutes, multiply the decimal fraction by 60 (e.g. 0.75 × 60 = 45 minutes).

Frequently Asked Questions
Payroll accounting systems calculate gross wages by multiplying hours worked by an hourly dollar rate (Hours × Hourly Rate = Gross Pay). Because currency is a base-10 decimal system, clock minutes (which are base-60) must be converted into decimal fractions of an hour.
