## 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 9.8 days into years we have to multiply 9.8 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

9.8 d → T(yr)

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

T(yr) = 9.8 d × 0.0027397260273973 yr

T(yr) = 0.026849315068493 yr

The final result is:

9.8 d → 0.026849315068493 yr

We conclude that 9.8 days is equivalent to 0.026849315068493 years:

9.8 days = 0.026849315068493 years
