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 240 hours into seconds we have to multiply 240 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

240 hr → T_(s)

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

T_(s) = 240 hr × 3600 s

T_(s) = 864000 s

The final result is:

240 hr → 864000 s

We conclude that 240 hours is equivalent to 864000 seconds:

240 hours = 864000 seconds
