## 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 42.5 years into seconds we have to multiply 42.5 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

42.5 yr → T(s)

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

T(s) = 42.5 yr × 31536000 s

T(s) = 1340280000 s

The final result is:

42.5 yr → 1340280000 s

We conclude that 42.5 years is equivalent to 1340280000 seconds:

42.5 years = 1340280000 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 7.4611275255917E-10 × 42.5 years.

Another way is saying that 42.5 years is equal to 1 ÷ 7.4611275255917E-10 seconds.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that forty-two point five years is approximately one billion three hundred forty million two hundred eighty thousand seconds:

42.5 yr ≅ 1340280000 s

An alternative is also that one second is approximately zero times forty-two point five years.
