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 3.9 hours into seconds we have to multiply 3.9 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
3.9 hr → T(s)
Solve the above proportion to obtain the time T in seconds:
T(s) = 3.9 hr × 3600 s
T(s) = 14040 s
The final result is:
3.9 hr → 14040 s
We conclude that 3.9 hours is equivalent to 14040 seconds:
3.9 hours = 14040 seconds
