Minutes to Hours Conversion Chart
On this page
Use this chart to convert minute values into decimal hours and HH:MM duration. The exact formula is minutes / 60. The two-decimal column is a display value; values such as 1/60 repeat and are rounded.

How the chart is calculated
Divide minutes by 60. For 41 minutes, 41/60 = 0.683333..., which displays as 0.68 at two decimals. For 45 minutes, 45/60 = 0.75 exactly.
The chart is a lookup aid, not a policy table. If you need a live calculation, use the Minutes to Hours Converter. If a payroll system requests a particular two-decimal convention, compare its documentation with the Payroll Minutes-to-Decimal Chart.
Exact values versus two-decimal values
Two decimals cannot represent every minute perfectly. One minute is exactly 1/60 hour, but 0.02 hour equals 1.2 minutes. Preserve the original minute total or a higher-precision value when the result will be converted back later.
Common mistakes
- Do not divide by 100. Forty-five minutes is 0.75 hour, not 0.45.
- Do not read 1.30 as 1:30. It equals 1 hour 18 minutes.
- Do not add rounded line items when the exact total is available.
- Do not apply a payroll interval merely because a two-decimal chart is shown.
