## Conversion formula

The conversion factor from hours to seconds is 3600, which means that 1 hour is equal to 3600 seconds:

1 hr = 3600 s

To convert 5 hours into seconds we have to multiply 5 by the conversion factor in order to get the time amount from hours to seconds. We can also form a simple proportion to calculate the result:

1 hr → 3600 s

5 hr → T(s)

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

T(s) = 5 hr × 3600 s

T(s) = 18000 s

The final result is:

5 hr → 18000 s

We conclude that 5 hours is equivalent to 18000 seconds:

5 hours = 18000 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 5.5555555555556E-5 × 5 hours.

Another way is saying that 5 hours is equal to 1 ÷ 5.5555555555556E-5 seconds.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hours is approximately eighteen thousand seconds:

5 hr ≅ 18000 s

An alternative is also that one second is approximately zero times five hours.
