When you need to convert hours to years
- Converting durations in project plans, billing sheets and race results.
- Setting timeouts, cache lifetimes and cron intervals in software.
Common mistakes to avoid
- Dividing when you should multiply. Because 1 hour = 0.000114 years, the answer should be smaller than the number you started with.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.
How these units are defined
- Hour (h): Sixty minutes. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Year (yr): An average Gregorian year (365.2425 days). The accepted value is a measured or conventional figure rather than an exact definition, so the factor shown is rounded.
