## 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 9 days into years we have to multiply 9 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

9 d → T_{(yr)}

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

T_{(yr)} = 9 d × 0.0027397260273973 yr

T_{(yr)} = 0.024657534246575 yr

The final result is:

9 d → 0.024657534246575 yr

We conclude that **9 days is equivalent to 0.024657534246575 years**:

9 days = 0.024657534246575 years
