How to convert decimal hours to hours and minutes
Keep the whole number as hours, then multiply the decimal part by 60 to get minutes:
hours = floor(d); minutes = round((d − hours) × 60)
So 1.75 becomes 1 hour and 45 minutes. This is the reverse of the decimal conversion used on timesheets.
The exact values people look up most
1.75 in hours is 1 hour 45 minutes — probably the single most-looked-up decimal on pay stubs. 1.5 hours is 1 hour 30 minutes. 2.5 hours is 2 hours 30 minutes. 0.75 hours is 45 minutes, 0.5 hours is 30 minutes, and 0.25 hours is 15 minutes.
One value trips people up: 0.3 hours is 18 minutes, not 30 — the part after the point counts sixtieths of an hour, so multiply it by 60. Thirty minutes as a decimal is 0.50.
Any value ending in .25, .50, or .75 converts on sight (15, 30, or 45 minutes). Everything else, type into the converter above.
Reading a pay stub in decimal hours
Pay stubs and payroll reports list hours in decimal form, which is compact but not how anyone thinks about their day. A line reading 86.67 hours for a two-week period is awkward to picture; converting it gives 86 hours 40 minutes, and the extra 6.67 hours over 80 stand out immediately as overtime once you see them.
The trick that makes this fast: the decimal part is sixtieths. To read 0.67, ask what fraction of 60 it is: 0.67 × 60 ≈ 40 minutes. Landmarks help too: .25 is 15 minutes, .50 is 30, and .75 is 45. More than half the decimals you will meet on a pay stub are one of those three.
Spotting errors in a payroll total
Converting back is also a quick audit. Suppose you know you worked five 8-hour days and one 4-hour day, and payroll reports 44.25 hours. Converting 44.25 gives 44 hours 15 minutes, but your own count is 44 hours flat. The 15-minute difference is small enough to hide in a rounding rule and big enough to be worth asking payroll about.
For the rules employers are allowed to round by, see the time card rounding guide; for how overtime hours get calculated from these decimals, see the overtime guide.

Frequently asked questions
What is 1.75 in hours?
1.75 decimal hours is 1 hour 45 minutes. The whole number 1 is the hours, and 0.75 × 60 = 45 minutes. Enter 1.75 above to confirm.
What is 2.5 hours in hours and minutes?
2.5 hours = 2 hours 30 minutes (0.5 × 60 = 30). It is a common value on pay stubs for a two-and-a-half-hour shift or meeting block.
What is 0.3 hours?
0.3 hours is 18 minutes (0.3 × 60 = 18). Note it is not 30 minutes — thirty minutes is 0.50 decimal hours.
What is 1.5 hours in hours and minutes?
1.5 hours = 1 hour 30 minutes. Half an hour is 0.50, so any x.5 value is x hours plus exactly 30 minutes.
What is 3.5 hours in hours and minutes?
3.5 hours = 3 hours 30 minutes, the same pattern as 1.5 and 2.5: the .5 after the point is always 30 minutes.
How do I read 2.25 hours?
2.25 hours = 2 hours 15 minutes (0.25 × 60 = 15). Decimal hours split the fractional part into minutes this way.
What does 7.67 hours mean on my pay stub?
0.67 × 60 = 40.2, so 7.67 hours is 7 hours and about 40 minutes, most likely a shift of 7 hours 40 minutes (7 + 40 ÷ 60 = 7.6667, rounded to 7.67). Any two-place decimal can be read this way: multiply the part after the point by 60.
Why would I convert decimal hours back to hours and minutes?
When a timesheet shows 7.5 hours, it helps to see that as 7 hours 30 minutes to plan a shift or compare it with a clock-in time. Payroll math wants decimals; humans planning their day think in hours and minutes.
Is 0.25 hours 25 minutes?
No, 0.25 hours is 15 minutes. Twenty-five minutes is 25 ÷ 60 = 0.4167 decimal hours. The decimal part of an hour counts sixtieths, so multiply it by 60 to get minutes.
How do I convert a weekly total like 38.42 hours?
The whole number stays: 38 hours. The fraction: 0.42 × 60 = 25.2, about 25 minutes. So 38.42 hours is roughly 38 hours 25 minutes across the week. The converter above does the same math for any value, to the minute.
How do I go the other way, minutes to decimal?
Use the Minutes to Decimal Converter to turn hours and minutes into a single decimal number.
Does this work for values over 24 hours?
Yes. 45.75 decimal hours is 45 hours 45 minutes. Decimal hours are a duration, not a clock time, so there is no 24-hour limit to worry about.
