## 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 15.2 hours into seconds we have to multiply 15.2 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

15.2 hr → T(s)

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

T(s) = 15.2 hr × 3600 s

T(s) = 54720 s

The final result is:

15.2 hr → 54720 s

We conclude that 15.2 hours is equivalent to 54720 seconds:

15.2 hours = 54720 seconds
