The conversion factor from days to years is 0.0027379070069885, which means that 1 day is equal to 0.0027379070069885 years:

1 d = 0.0027379070069885 yr

To convert 18.1 days into years we have to multiply 18.1 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 → 0.0027379070069885 yr

18.1 d → T(yr)

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

T(yr) = 18.1 d × 0.0027379070069885 yr

T(yr) = 0.049556116826492 yr

The final result is:

18.1 d → 0.049556116826492 yr

We conclude that 18.1 days is equivalent to 0.049556116826492 years:
