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 0.5 hours into seconds we have to multiply 0.5 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
0.5 hr → T(s)
Solve the above proportion to obtain the time T in seconds:
T(s) = 0.5 hr × 3600 s
T(s) = 1800 s
The final result is:
0.5 hr → 1800 s
We conclude that 0.5 hours is equivalent to 1800 seconds:
0.5 hours = 1800 seconds
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 0.00055555555555556 × 0.5 hours.
Another way is saying that 0.5 hours is equal to 1 ÷ 0.00055555555555556 seconds.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that zero point five hours is approximately one thousand eight hundred seconds:
0.5 hr ≅ 1800 s
An alternative is also that one second is approximately zero point zero zero one times zero point five hours.
