Decimal Hours Converter
Payroll counts in hundredths of an hour, clocks count in minutes. Convert either way, or look it up in the chart.
Minutes to decimal hours chart
Rounded to two places, as most payroll systems do. Some employers round to tenths instead (6-minute increments: 0.1 h per 6 minutes).

A payroll example
Monday 7 h 50 min, Tuesday 8 h 10 min, Wednesday 8 h 25 min. In decimals that is 7.83 + 8.17 + 8.42 = 24.42 hours. At $19 an hour, 24.42 × $19 = $463.98. Totalling the minutes first (24 h 25 min = 24.4167 h) gives $463.92; the few cents’ difference comes from rounding each day, which is why many payroll systems round only the weekly total. The time card calculator keeps exact minutes until the end.
Remember that hours are not decimal numbers: 8.45 hours is 8 h 27 min. The explainer on the hours calculator page shows how much that confusion can cost.
Questions people ask
How do I convert minutes to decimal hours?
Divide the minutes by 60. 15 minutes = 0.25 hours, 30 = 0.5, 45 = 0.75, 20 = 0.33. For a full time like 7 h 20 min, it is 7 + 20 ÷ 60 = 7.33 hours.
How do I convert decimal hours to hours and minutes?
Keep the whole number as hours and multiply the decimal part by 60. 7.8 hours = 7 hours + 0.8 × 60 minutes = 7 h 48 min.
How do I convert hours to minutes?
Multiply by 60. 2.5 hours × 60 = 150 minutes; 8 hours = 480 minutes.
Why does payroll use decimal hours?
Because pay is hours × rate, and you can only multiply a rate by a decimal number. 7 h 30 min at $20 is 7.5 × $20 = $150; multiplying 7.30 × $20 would give $146, which is wrong.
