⏱️ Minutes to Hours Converter
Convert minutes to hours and back. The exact factor, a table of the values people look up most, and what each unit is actually used for.
Converting minutes to hours
One minute is 0.01666666667 hours, and one hour is 60 minutes.
hours = minutes × 0.01666666667
Getting the precision right
The conversion is a division by 60, and the pitfall is decimal against sexagesimal. 1 hour 30 minutes is 1.5 hours, but 1 hour 15 minutes is 1.25 hours, not 1.15. Writing 1.15 on a timesheet when you mean 1 hour 15 is a mistake that costs nine minutes of pay every time.
Where each unit is used
Timesheets, billing, cooking and exercise logs all mix the two. Payroll is the case where it matters most, because hours are usually paid in decimal form while people record their time in minutes.

Where the two units came from
The division into 60 is Babylonian, and it survives because 60 divides evenly by 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30 — which matters enormously when you are dividing time by hand without decimals. The names come from medieval Latin: pars minuta prima, the first small part of an hour, and pars minuta secunda, the second small part. That is literally all a second is, the second-level subdivision.
Round the result to the precision your own work needs. These converters carry the full factor, which is useful for checking but rarely what you want to write down.
Once you have this figure, the days to hours is where it usually goes next. the mb to gb is the related one people reach for afterwards.
Frequently Asked Questions (FAQs)
How do I convert minutes to decimal hours?
Divide by 60. So 45 minutes is 0.75 hours and 20 minutes is 0.333 hours. For payroll, this decimal figure is what most systems expect.
Why is 1 hour 15 minutes not 1.15 hours?
Because minutes run to 60, not 100. Fifteen minutes is a quarter of an hour, so the decimal is 1.25. Writing 1.15 understates the time by nine minutes, which is the single most common timesheet error.
How do I convert the other way?
Multiply the decimal part by 60. For 2.4 hours, 0.4 times 60 is 24, so it is 2 hours 24 minutes.
