Minutes to Decimal Conversion Chart

To turn minutes into decimal hours, divide the minutes by 60. The result is the decimal form payroll expects on a timesheet.

Example: 20 minutes = 20 ÷ 60 = 0.33 decimal hours.

Most timesheets keep two decimal places, so 0.3333 is written as 0.33. Use the converter above for any value, or scan the chart below for the common ones.

A few values show up constantly on timesheets, so they are worth memorizing: 15 minutes = 0.25, 20 minutes = 0.33, 30 minutes = 0.50, and 45 minutes = 0.75. When a shift has an odd length, the chart above or the converter handles it exactly.

20 minutes in decimal is 0.33 (20 ÷ 60 = 0.3333, rounded to two places). 25 minutes in decimal is 0.42 (0.4167 exact). 40 minutes in decimal is 0.67 (0.6667 exact). 45 minutes in decimal is 0.75 — one of the cleanest values on the whole chart. 50 minutes in decimal is 0.83 (0.8333 exact), and 35 minutes in decimal is 0.58 (0.5833 exact).

Every other minute from 1 to 60 is in the chart above, and the converter at the top of this page handles values beyond an hour — 90 minutes is 1.50, for example, because the whole hours carry over.

The 1–60 table above prints on a single page from any browser (File → Print, or Ctrl/Cmd + P). The two-column layout comes out clean without ads or navigation, which is why many people keep a copy taped near the time clock, inside a timesheet binder, or on the fridge door of a break room.

If you came here for one exact value, here are the decimal forms people look up most: 20 minutes in decimal is 0.33 (20 ÷ 60 = 0.3333, rounded to two places), 18 minutes in decimal is 0.30 (18 ÷ 60 = 0.30 exactly), and 45 minutes in decimal is 0.75. Other frequent ones are 15 minutes = 0.25, 30 minutes = 0.50, and 90 minutes = 1.50 (1 hour 30 minutes). The full 1–60 chart above lists every minute, and the converter at the top handles any number instantly.
