To convert seconds to years (average), enter the value in the first field. The result in years (average) is calculated automatically using the exact conversion factor.

1 s ≈ 3.16887385068 × 10-8 yr
1 yr = 31556952 s

Formula: yr ≈ s × 3.16887385068 × 10-8
s = yr × 31556952

Definitions: 1 yr = 365.2425 d

The second (s) is the SI base unit of time, defined by 9,192,631,770 cycles of the radiation of the cesium-133 atom. All other time units used in science and engineering are built on it.

The year here is the average Gregorian calendar year of 365.2425 days, or 31,556,952 seconds. Actual calendar years have 365 or 366 days, so the result for a specific year can differ by up to a day.
