Decimal to Time Converter

Because 7.75 hours is not the same as 7 hours 75 minutes, and someone's timesheet depends on knowing that.

Enter a decimal hour value, e.g. 7.75 or 1.5

7h 45m
7hours
:
45minutes

This tool converts decimal hours to hours and minutes, or hours and minutes back to a decimal. It works both ways, and it takes about two seconds.

Payroll software loves decimals. Humans don't. 7.75 hours looks like a typo until you realize it means 7 hours and 45 minutes. This comes up constantly on timesheets, invoices, and any system that stores time as a number rather than a clock. Type in the decimal and get the human-readable version, or go the other way if you need to enter time into a system that only accepts decimals.

How we work it out

Decimal to time: multiply the decimal by 60 to get total minutes, then split into hours and minutes. So 7.75 x 60 = 465 minutes, which is 7 hours and 45 minutes. Time to decimal: take the total minutes and divide by 60. So 7 hours 45 minutes = 465 minutes divided by 60 = 7.75.

Questions

Why do timesheets use decimal hours?

Because computers find it easier to do math with 7.75 than with "7 hours 45 minutes." Payroll systems multiply the decimal directly by an hourly rate, which is simpler than converting time first.

What does 0.25 hours mean?

15 minutes. Each quarter of an hour is 0.25. So 0.5 is 30 minutes, 0.75 is 45 minutes, and 1.0 is a full hour.

Can I convert hours over 24?

Yes. This tool isn't limited to a single day. If you worked 38.5 hours in a week, it'll tell you that's 38 hours and 30 minutes.
