Minutes to Decimal Hours Chart
All sixty minutes as decimal hours, to two and three places. Payroll systems take hours as a decimal, so 8 hours 27 minutes is entered as 8.45 — and the exact thirds, like 20 minutes at 0.3333, are where a two-place entry quietly loses money.
Source data and formula checked · How we check
Minutes to Decimal Hours Chart reads decimal hours straight off minutes, for 60 values from 0 to 59. Every row is computed from the same formula the calculator uses, not measured or copied from another table, so a value between two rows can be worked out the same way. The formula is the one published by 29 CFR 785.48(b).
Hours held at zero, so each row is the minutes alone. Add the whole hours back: 8 h 27 m is 8 + 0.45 = 8.45.

Questions people actually ask
- How do I read the Minutes to Decimal Hours Chart?
- Find your minutes in the first column and read across. At 0 the decimal hours is 0.00 h; at 59 it is 0.98 h. The table runs from 0 to 59 in 60 rows.
- How much does the decimal hours change per row?
- By 0.02 h for every 1 of minutes, and by the same amount everywhere in the table — the relationship is a straight line, so halfway between two rows is halfway between their two answers. That is what makes reading between the rows safe here.
- What if my minutes is outside the table?
- The chart covers 0 to 59, which is the range people actually look up. Anything above or below goes into the calculator, which takes any figure and shows each step of the working rather than only the result. Open the minutes to decimal.
- Where do these numbers come from?
- Every row is computed at build time from the formula published by 29 CFR 785.48(b), by the same code behind the calculator — not transcribed from another table, which is how a rounding error in one chart ends up in twenty.
Need a different number?
The chart covers the common values. For anything between the rows, the minutes to decimal takes any figure and shows the working.
