How it works and common questions

Common minutes to decimal hours

  • 5 minutes in decimal is 0.08 hours (5 ÷ 60).
  • 10 minutes in decimal is 0.17 hours (10 ÷ 60).
  • 15 minutes in decimal is 0.25 hours (15 ÷ 60).
  • 20 minutes in decimal is 0.33 hours (20 ÷ 60).
  • 25 minutes in decimal is 0.42 hours (25 ÷ 60).
  • 30 minutes in decimal (half an hour) is 0.50 hours.
  • 35 minutes in decimal is 0.58 hours (35 ÷ 60).
  • 40 minutes in decimal is 0.67 hours (40 ÷ 60).
  • 45 minutes in decimal is 0.75 hours (45 ÷ 60).
  • 50 minutes in decimal is 0.83 hours (50 ÷ 60).
  • 1 hour 30 minutes is 1.50 hours.
  • 7 hours 45 minutes is 7.75 hours — not 7.45.

How the conversion works

Decimal hours express minutes as a fraction of an hour: divide minutes by 60. So 15 minutes is 0.25, 30 minutes is 0.50, and 45 minutes is 0.75. Going the other way, multiply the fraction by 60: 8.33 hours is 8 hours plus 0.33 × 60 ≈ 20 minutes.

The classic payroll mistake is reading the clock digits as decimals — 7:45 is not 7.45 hours. At $20/hour that error underpays 7.75 − 7.45 = 0.30 hours, or $6.00, every single shift.

Why does payroll use decimal hours instead of hours and minutes?

Pay is calculated as hours × hourly rate, and that multiplication needs a decimal. 7:45 at $20/hour is 7.75 × $20 = $155.00 — treating 7:45 as “7.45” would underpay by $6.00.

What is the difference between rounding to 2 decimals and payroll rounding?

This chart shows exact values rounded to 2 decimal places. Some payroll systems instead round worked time to the nearest tenth of an hour (6-minute steps) or quarter hour (15-minute steps) before converting — check which policy your employer uses.

How do I convert decimal hours back to minutes?

Multiply the fraction by 60. For 7.75 hours: 0.75 × 60 = 45, so it’s 7 hours 45 minutes. The decimal-to-hours converter above handles any value, like 8.33 → 8h 20m.
