## 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 15.4 years into seconds we have to multiply 15.4 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

15.4 yr → T_{(s)}

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

T_{(s)} = 15.4 yr × 31536000 s

T_{(s)} = 485654400 s

The final result is:

15.4 yr → 485654400 s

We conclude that **15.4 years is equivalent to 485654400 seconds**:

15.4 years = 485654400 seconds

## Alternative conversion
