## 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 4 years into seconds we have to multiply 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

4 yr → T(s)

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

T(s) = 4 yr × 31536000 s

T(s) = 126144000 s

The final result is:

4 yr → 126144000 s

We conclude that 4 years is equivalent to 126144000 seconds:

4 years = 126144000 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 7.9274479959411E-9 × 4 years.

Another way is saying that 4 years is equal to 1 ÷ 7.9274479959411E-9 seconds.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four years is approximately one hundred twenty-six million one hundred forty-four thousand seconds:

4 yr ≅ 126144000 s

An alternative is also that one second is approximately zero times four years.
