## 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 1 hours into seconds we have to multiply 1 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

1 hr → T(s)

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

T(s) = 1 hr × 3600 s

T(s) = 3600 s

The final result is:

1 hr → 3600 s

We conclude that 1 hours is equivalent to 3600 seconds:

1 hours = 3600 seconds
