Years to Seconds - Convert yr to s

Years (yr) Conversion

A year is a unit of time defined as the period of time needed for the Earth to move through its orbit around the Sun. The course of a year sees the different seasons passing, weather changes, hours of daylight and so on. The average length of the calendar year is 365.2425 days or, to be even more precise, 31,556,925.9747 seconds.

Seconds (s) Conversion

A second is an SI base unit of time which is also a fundamental unit of time for all measuring systems. It was defined as 1/86400 of a solar day, which turned out to be not accurate because the solar day is not a constant. There is another intuitive understanding that a second is about the period between beats of a human heart.
