## 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 20.3 hours into seconds we have to multiply 20.3 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

20.3 hr → T_{(s)}

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

T_{(s)} = 20.3 hr × 3600 s

T_{(s)} = 73080 s

The final result is:

20.3 hr → 73080 s

We conclude that **20.3 hours is equivalent to 73080 seconds**:

20.3 hours = 73080 seconds
