Convert Hours to Years

1 hour is 0.000114 yr. One hour is exactly 0.000114079458625 years.

One hour is 1.1408 × 10^-4 years. To convert hours to years, multiply by 1.1408 × 10^-4; to go the other way, divide by 1.1408 × 10^-4 or multiply by 8765.82. This one is an average rather than an exact factor: a calendar year is 365 days or 366, so this figure is an average across the 400-year leap cycle. The definition comes from BIPM SI Brochure. Sixty minutes, and exactly 3,600 seconds.
