## 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 155 days into years we have to multiply 155 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

155 d → T(yr)

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

T(yr) = 155 d × 0.0027397260273973 yr

T(yr) = 0.42465753424658 yr

The final result is:

155 d → 0.42465753424658 yr

We conclude that 155 days is equivalent to 0.42465753424658 years:

155 days = 0.42465753424658 years
