To convert 3600 hours into seconds we have to multiply 3600 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

3600 hr → T_(s)

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

T_(s) = 3600 hr × 3600 s

T_(s) = 12960000 s

The final result is:

3600 hr → 12960000 s

We conclude that 3600 hours is equivalent to 12960000 seconds:
