To convert minutes to decimal hours, divide the minutes by 60. So 15 minutes is 0.25, 30 minutes is 0.50, and 45 minutes is 0.75. The full table is below.

Minutes to decimal hours: full conversion table

Payroll runs on decimal hours, not hours and minutes. The rule is simple: divide the minutes by 60. 30 minutes is 0.50 hours, not 0.30. 20 minutes is 0.33 hours. Getting this wrong is one of the most common reasons a timesheet total does not match payroll.

The conversions everyone needs

15 minutes = 0.25 hours
20 minutes = 0.33 hours
30 minutes = 0.50 hours
45 minutes = 0.75 hours
50 minutes = 0.83 hours

The 2-decimal column is what most payroll systems use. The 4-decimal column is the exact value if you need to avoid rounding drift across many entries.

Skip the conversion entirely

Kangaroo Clock's CSV export already gives you a duration_hours column in decimal, computed from the exact seconds of each shift, so you never convert by hand. If hand-totals and payroll disagree, see why the hours don't add up. Prefer a calculator? Try the free time card calculator.
