Conversion formula
How to convert 420 weeks to years?

We know (by definition) that: 1 wk ≈ 0.019165365 yr.

We can set up a proportion to solve for the number of years.

1 wk / 420 wk ≈ 0.019165365 yr / x yr

Now, we cross multiply to solve for our unknown x:

x yr ≈ (420 wk / 1 wk) * 0.019165365 yr → x yr ≈ 8.0494533 yr

Conclusion:

420 wk ≈ 8.0494533 yr

Conversion in the opposite direction

The inverse of the conversion factor is that 1 year is equal to 0.124232040401701 times 420 weeks.

Approximation

An approximate numerical result would be: four hundred and twenty weeks is about eight point zero five years, or alternatively, a year is about zero point one two times four hundred and twenty weeks.

Units involved

This is how the units in this conversion are defined:

Weeks

"A week is a time unit equal to seven days. It is the standard time period used for cycles of rest days in most parts of the world, mostly alongside—although not strictly part of—the Gregorian calendar. The days of the week were named after the classical planets (derived from the astrological system of planetary hours) in the Roman era. In English, the names are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday."

Years

"A year is the orbital in which Earth moves in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the globe, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked."
