Choose a direction. For hours and minutes to decimal, enter those two fields; the decimal-hours field is ignored. In the reverse direction, enter decimal hours instead.
Minutes are a fraction of 60, not decimal digits. The remaining-minutes result keeps fractional minutes instead of rounding to whole minutes.

Some employers round to the nearest tenth or quarter hour, so a payroll figure may differ slightly. Decimal conversion assumes minutes divide evenly into 60, and long repeating decimals such as 10 minutes being 0.1667 hour need rounding.

Common error: Typing the minutes after a decimal point. 7.45 hours means 7 hours and 27 minutes, so a time entered that way is off by 18 minutes.

Payroll and billing systems run on decimal hours, and a clock reading is not a decimal. Seven hours and 45 minutes is 7.75 hours, because 45 is three quarters of 60. Reading it as 7.45 underpays the worker by a quarter of an hour.
The total minutes output shows the same time as one whole number, 465, which is handy for reports that count minutes.
Divide the minutes by 60, not by 100. Fifteen minutes is 0.25, thirty is 0.50 and forty-five is 0.75.
Convert back on the decimal to time calculator, calculate shifts on the time card and time duration pages, and compute overtime on the overtime pay calculator. The gross pay page turns hours and rates into pay. Payroll rounding rules can affect the paid total compared with exact elapsed time.

Convert decimal hours into hours and minutes. Read a payroll figure such as 7.75 hours as a time on the clock.

The result reads the decimal as hours and minutes. 7.75 hours is 7 hours and 45 minutes, or 465 minutes in total. Common decimals to remember: 0.25 is 15 minutes, 0.5 is 30 minutes and 0.75 is 45 minutes.
Use it to check a pay stub, to make sense of a spreadsheet of hours or to convert a duration for scheduling. The reverse direction is on the hours to decimal calculator.
Enter the decimal hours, such as 7.75 from a timesheet or a spreadsheet. The tool separates the whole hours and converts the fraction into minutes by multiplying by 60. Use it when a report or payroll system gives hours as decimals and you want to read them as hours and minutes on a clock.
For a value with many decimals, the minutes are rounded to the nearest whole minute.
Payroll gives time as a decimal, and the clock needs hours and minutes. Take the whole part as hours and multiply the remainder by 60: 7.75 hours is 7 hours and 45 minutes. It is the reverse of entering a timesheet.
The total in minutes, 465, is handy for reports that add up minutes across several workers and only then turn them back into hours.
Multiply the decimal part by 60, not by 100. A decimal of 0.5 is thirty minutes, not fifty.
Reading 7.75 as 7 hours and 75 minutes. The digits after the decimal point are a fraction of an hour, not a count of minutes.
Convert the other way on the hours to decimal calculator, and calculate elapsed time on the time duration page. The time card, overtime pay and gross pay calculators use hours in pay calculations. The add time page adds durations to clock times.
How do I convert decimal hours to minutes?
Multiply the decimal part by 60. 0.75 hours is 45 minutes, and 0.2 hours is 12 minutes.
What is 0.1 of an hour?
Six minutes. Tenths of an hour are common in billing, where each 0.1 is six minutes.
Why do timesheets use decimal hours?
Because they make pay calculations simple: hours multiplied by the hourly rate, without converting minutes each time.

Rounding can create small differences of a minute or so when converting back and forth. Some systems track hours in hundredths, and others in tenths. The tool does not add breaks or overtime.
A decimal larger than 24 is fine as a duration but not as a time of day.
Does 7.999 hours become 8 hours automatically?
No. It is seven whole hours plus 59.94 minutes. Any payroll rounding rule is a separate step.
Which fields affect the answer?
The selected direction determines the active representation: decimal hours, or separate hours and minutes. The other representation is ignored.
How do I convert minutes to a decimal of an hour?
Divide the minutes by 60. 45 minutes is 0.75 hours, and 15 minutes is 0.25 hours.
Why is 7 hours 45 minutes not 7.45 hours?
Because an hour has 60 minutes, not 100, so 45 minutes is 0.75 of an hour. Writing 7.45 would mean about 7 hours 27 minutes.
How do I round decimal hours for billing?
Follow your agreement. Many use quarter hours or tenths of an hour, and rounding should be applied consistently.
