Decimal Hours Conversion Chart
A complete reference for converting minutes to decimal hours. Use this when calculating payroll, completing timesheets, or verifying paycheck math.
The Formula
Decimal Hours = Whole Hours + (Minutes ÷ 60)
Examples: 7h 30min = 7 + 30/60 = 7.50 | 8h 15min = 8 + 15/60 = 8.25 | 6h 45min = 6 + 45/60 = 6.75
Why Payroll Uses Decimal Hours
Payroll systems calculate wages by multiplying hours × rate. Decimal notation makes this arithmetic exact and avoids rounding issues. For example, 7 hours 45 minutes as 7.75 × $20/hr = $155.00 exactly. Keeping time in hours:minutes format requires an extra conversion step that introduces rounding opportunities.
