About Kilowatt
One kilowatt is 1,000 W. Motor, heater, and grid-scale loads are often rated in kW.
About Foot-pound per Second
Foot-pounds per second is a mechanical power rate: 1 ft·lb/s = 1.3558179483314004 W (exactly, from the international foot definition).
How to convert kilowatts to foot-pounds per second
1 kilowatt is equal to 737.56214927726535 foot-pound per second when both are expressed in watt-equivalents:
1 kw = (1,000 W ÷ 1.3558179483314003 W) ft_lb_s = 737.56214927726535 ft_lb_s
Each kilowatt is defined as 1,000 W and each foot-pound per second as 1.3558179483314003 W in this tool, so one kw equals 1,000 ÷ 1.3558179483314003 ft_lb_s = 737.56214927726535 ft_lb_s.
Let d(kw) be the numeric value in Kilowatt (kw), and d(ft_lb_s) the value in Foot-pound per Second (ft_lb_s). Then:
d(ft_lb_s) = d(kw) × (1,000 / 1.3558179483314003)
Equivalently, divide by how many kw fit into one ft_lb_s (watts per ft_lb_s divided by watts per kw):
d(ft_lb_s) = d(kw) ÷ 0.00135581794833
Or: foot-pound per second = kilowatt ÷ 0.00135581794833
Examples
Example #1: Convert 1 kw to foot-pound per second
1 kw = 1 kw × (1,000/1.3558179483314003) ft_lb_s = 737.562149277 ft_lb_s
1 kw = 1 kw ÷ 0.00135581794833 = 737.562149277 ft_lb_s
Intermediate watts: 1,000 W
Example #2: Convert 10 kw to foot-pound per second
10 kw = 10 kw × (1,000/1.3558179483314003) ft_lb_s = 7375.62149277 ft_lb_s
10 kw = 10 kw ÷ 0.00135581794833 = 7375.62149277 ft_lb_s
Intermediate watts: 10,000 W
Summary
To convert Kilowatt to Foot-pound per Second, multiply the value in kw by the ratio of watts per kw divided by watts per ft_lb_s. Equivalently: value_ft_lb_s = value_kw × (1000 / 1.3558179483314003). Numerically, 1 kw equals 737.5621492772653 ft_lb_s.
Relationship context
You are converting between SI / decimal power (watts and prefixes) (Kilowatts) and mechanical power (horsepower, ft·lb/s) (Foot-pounds per Second). All linear values are mapped through watts first. The numeric factor is 7.375621e+2.
