The conversion of hours into seconds must be performed by multiplying the number of hours by 3,600.
The 3,600 factor used is due to the simple fact that each hour has 3,600 seconds, after all, each hour has 60 minutes, and each minute has 60 seconds, so:
If 1 hour has 60 minutes and each minute has 60 seconds, we multiply: 60 minutes x 60 seconds = 3,600 seconds.
