Converting minutes by hand? InstaClock tracks and totals your time for you

Payroll and timesheets want time in decimal hours, not minutes: 20 minutes is 0.33 of an hour, not 0.20. Type any minute value and this converter gives you the decimal instantly, and the reference chart below covers every five-minute step so you can look up the common ones at a glance. To convert a full time like 7h 30m — or go from decimal back to hours and minutes — use the decimal hours converter instead.

The method

How this calculation works

  1. 01Divide the number of minutes by 60 — that is the fraction of an hour.
  2. 02So 20 minutes is 20 ÷ 60 = 0.33 hours, and 45 minutes is 45 ÷ 60 = 0.75 hours.
  3. 03The result is rounded to two decimal places, which is what payroll exports use.
  4. 04For values over 60 minutes the decimal simply grows (90 minutes = 1.50 hours).
  • Decimal minutes are not the clock reading: 0.20 is not 20 minutes — 20 minutes is 0.33.
  • Common values: 5m = 0.08, 10m = 0.17, 15m = 0.25, 30m = 0.50, 45m = 0.75.
  • Rounding to two places means a few minute values share a decimal (e.g. 20m and 21m both show ~0.34); use the exact figure where precision matters.
  • This converts a duration in minutes, so values are always treated as positive.

Frequently asked questions

How do you convert minutes to decimal hours?
Divide the minutes by 60. For example, 20 minutes is 20 ÷ 60 = 0.33 hours and 45 minutes is 0.75 hours. The chart on this page lists every five-minute step so you can look up the common ones without doing the maths.
What is 20 minutes as a decimal?
20 minutes is 0.33 hours (20 ÷ 60), not 0.20. This is the most common mix-up — the decimal is a fraction of an hour, not the minute count with a dot in front.
Is 15 minutes 0.15 in decimal?
No. 15 minutes is a quarter of an hour, so it is 0.25 in decimal, not 0.15. Likewise 30 minutes is 0.50 and 45 minutes is 0.75.
How does this differ from the decimal hours converter?
This page converts a plain minute value and gives you a lookup chart. The decimal hours converter handles a full time in hours and minutes (like 7h 30m) and also converts decimal hours back into hours and minutes.
