Hour Converters

Convert hours to minutes, seconds, milliseconds, days, weeks, months and years.

What this tool does

Convert hours to minutes, seconds, milliseconds, days, weeks, months and years. Type an amount in hours, choose the units, and the tool converts it to minutes. It offers 9 time units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 9 options, including Millisecond, Second, Minute, Hour, Day, Week. Starts as Hour.
  • To: Choose one of the same 9 units as "From". Starts as Minute.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from hours to minutes:

  • 1 h = 60 min
  • 5 h = 300 min
  • 10 h = 600 min
  • 50 h = 3,000 min
  • 100 h = 6,000 min

Multiply the number of hours by 60 to get minutes. Both units are exact definitions, so 60 is the exact factor: 1 h = 60 min.

Limitations

  • Converts a length of time between units. It does not work out the time between two calendar dates.
  • Months and years are averages, not the length of any particular calendar month or year.

FAQs

Q: How many minutes are in one hour?
A: One hour is 60 minutes. Change the From and To boxes to convert any other pair of units.
Q: Can I convert the other way, from minutes to hours?
A: Yes. Swap the From and To units. One minute is 1/60 of an hour, about 0.0167 hours.
Q: How long is a month or a year here?
A: A month is the average Gregorian month, 30.436875 days, and a year is the average Gregorian year, 365.2425 days (97 leap years in every 400 years). Real months and years vary in length, so these are averages. The Julian year of exactly 365.25 days is also in the list.
