## 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 345 years into seconds we have to multiply 345 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

345 yr → T(s)

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

T(s) = 345 yr × 31536000 s

T(s) = 10879920000 s

The final result is:

345 yr → 10879920000 s

We conclude that 345 years is equivalent to 10879920000 seconds:
