## Conversion formula

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 520 days into years we have to multiply 520 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

520 d → T(yr)

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

T(yr) = 520 d × 0.0027397260273973 yr

T(yr) = 1.4246575342466 yr

The final result is:

520 d → 1.4246575342466 yr

We conclude that 520 days is equivalent to 1.4246575342466 years:

520 days = 1.4246575342466 years
