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 18 hours into seconds we have to multiply 18 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
18 hr → T(s)
Solve the above proportion to obtain the time T in seconds:
T(s) = 18 hr × 3600 s
T(s) = 64800 s
The final result is:
18 hr → 64800 s
We conclude that 18 hours is equivalent to 64800 seconds:
18 hours = 64800 seconds
