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 340 hours into seconds we have to multiply 340 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

340 hr → T_(s)

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

T_(s) = 340 hr × 3600 s

T_(s) = 1224000 s

The final result is:

340 hr → 1224000 s

We conclude that 340 hours is equivalent to 1224000 seconds:

340 hours = 1224000 seconds
