## 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 7.2 hours into seconds we have to multiply 7.2 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

7.2 hr → T(s)

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

T(s) = 7.2 hr × 3600 s

T(s) = 25920 s

The final result is:

7.2 hr → 25920 s

We conclude that 7.2 hours is equivalent to 25920 seconds:

7.2 hours = 25920 seconds
