Decimal to Minutes Chart
Every decimal hour from 0.01 to 0.99, converted to minutes. Highlighted values (every .05 increment) convert to a whole minute with no rounding. Use your browser's print dialog (Ctrl/Cmd + P) to print or save this page as a PDF.
Prefer typing one value at a time instead of scanning a grid? Use the decimal to minutes calculator for that, or the minutes to decimal chart to look up the reverse direction.

How to read this chart
Find the decimal hour you have along the grid, and the number underneath it is the equivalent number of minutes. The grid runs left to right, top to bottom, in increasing order from 0.01 up to 0.99, so a value like 0.42 sits a little under halfway through.
The highlighted cells, appearing every fifth value in the sequence, are the 0.05 increments: 0.05, 0.10, 0.15, and so on up to 0.95. These are the only values that convert to a whole minute with nothing rounded off, since 0.05 of an hour is exactly 3 minutes. Every other cell has already been rounded to the nearest whole minute for readability.
Where this chart is used
A single conversion is easy to do in your head or with the calculator on the homepage, but a full chart earns its place when someone needs to check many values at once: a payroll administrator auditing a batch of timesheet entries, a manager spot-checking a week of decimal hours against clock punches, or anyone who wants a printed sheet taped up near a time clock instead of opening a calculator for every entry.
Common mistakes reading this chart
The chart itself is exact, but a dense grid still trips people up in predictable ways.
Looking up the whole decimal instead of just the fraction
This chart only covers 0.01 through 0.99. For a value like 2.42, look up 0.42 (25 minutes) and add the 2 whole hours (120 minutes) separately, for 145 minutes total.
Assuming every cell is an exact conversion
Only the highlighted 0.05 increments land on a whole minute with nothing rounded off. Every other cell already carries a small rounding adjustment.
Misreading a neighboring cell on a dense grid
With 99 values packed into a compact grid, it's easy for your eye to land one cell off from the value you meant to check, especially on a printed page instead of a screen.
Mixing rounding standards across two printed copies
If two people are comparing numbers from different printouts of a similar chart, check that both used the same rounding rule; a chart rounding to the nearest 6 minutes won't match one rounding to the nearest whole minute.
Frequently asked questions
Common questions about converting between decimal hours and minutes.
Why does the chart stop at 0.99?
0.99 is the highest fractional decimal below a full hour. Whole hours (1, 2, 3, and so on) just add 60 minutes each on top of whatever the decimal part converts to, so the fractional part is the only piece that actually needs a lookup chart.
What does the highlighted border on some cells mean?
A highlighted cell falls on a 0.05 increment (0.05, 0.10, 0.15, and so on), which always converts to an exact whole number of minutes with no rounding, since 0.05 of an hour is exactly 3 minutes. Cells without the highlight still convert correctly; the underlying minute value was just rounded to the nearest whole number.
Can I print this chart?
Yes. Use the print button above, or your browser's print dialog (Ctrl or Cmd + P), to print the page or save it as a PDF for a desk or break room reference.
Why isn't every value a round number of minutes?
Minutes only divide evenly into a decimal hour when the decimal is a multiple of 1/60 (about 0.0167). Most decimals people write, like 0.2 or 0.4, don't land on that grid exactly, so the chart shows the nearest whole minute.
How is this different from the minutes to decimal chart?
This chart starts from a decimal hour and looks up the minutes. The minutes to decimal chart runs the other direction, starting from a minute value and looking up the decimal. Use whichever one matches the number you already have.
What is 0.33 on this chart?
0.33 converts to 20 minutes (0.33 × 60 = 19.8, rounded to 20), one of the values without the exact-match highlight since the underlying fraction repeats.
What is 0.5 on this chart?
0.5 converts to exactly 30 minutes (0.5 × 60 = 30), one of the highlighted landmark values since it lands on a whole minute with no rounding.
Is this chart accurate enough for payroll?
Yes, for the fractional part. Each value is rounded to the nearest whole minute, which matches how most payroll systems already round decimal hours before displaying them. If your system rounds to a different increment, like the nearest quarter hour, the chart's minute figure may differ slightly from what a paycheck shows.
Can I use this chart for values above 0.99?
Not directly, but you don't need to. A decimal hour like 3.42 splits into a whole-hour part (3, worth 180 minutes) and a fractional part (0.42, looked up on this chart as 25 minutes), added together for 205 minutes total.
