The conversion factor from days to years is 0.0027397260273973, which means that 1 day is equal to 0.0027397260273973 years:

1 d = 0.0027397260273973 yr

To convert 422 days into years we have to multiply 422 by the conversion factor in order to get the time amount from days to years. We can also form a simple proportion to calculate the result:

1 d → 0.0027397260273973 yr

422 d → T(yr)

Solve the above proportion to obtain the time T in years:

T(yr) = 422 d × 0.0027397260273973 yr

T(yr) = 1.1561643835616 yr

The final result is:

422 d → 1.1561643835616 yr

We conclude that 422 days is equivalent to 1.1561643835616 years:

422 days = 1.1561643835616 years
