## Conversion formula

The conversion factor from years to seconds is 31536000, which means that 1 year is equal to 31536000 seconds:

1 yr = 31536000 s

To convert 9.8 years into seconds we have to multiply 9.8 by the conversion factor in order to get the time amount from years to seconds. We can also form a simple proportion to calculate the result:

1 yr → 31536000 s

9.8 yr → T(s)

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

T(s) = 9.8 yr × 31536000 s

T(s) = 309052800 s

The final result is:

9.8 yr → 309052800 s

We conclude that 9.8 years is equivalent to 309052800 seconds:

9.8 years = 309052800 seconds

## Alternative conversion
