How to use
- Type the time value in the box for the unit you have, for example hours.
- Every other unit — seconds to years — fills in at the same time.
- Change the number or the unit and all results update by themselves.
- Work backwards from years to minutes when you need a big span broken into small units.
Tips
- A month is counted as one twelfth of a year, so 365.25 days — leap years are covered.
- Handy for contracts: 18 months converts to about 547.9 days.
- Work backwards from years to minutes when breaking a large time span into small units.
Note
A month is taken as the average Gregorian month (one twelfth of a year) and a year as 365.25 days, so leap years are covered too.
