How to Convert Hours and Minutes to Decimal Hours

Payroll systems require hours in decimal format (e.g., 7.75 hours instead of 7 hours 45 minutes). To convert minutes into decimals:

Decimal Hours = Hours + (Minutes ÷ 60)

Common payroll minute conversions:

15 minutes = 0.25 hours
30 minutes = 0.50 hours
45 minutes = 0.75 hours
