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).
About Watt
The watt is the SI unit of power (one joule per second). All linear units in this converter are defined by a fixed watt equivalent.
How to convert foot-pounds per second to watts
1 foot-pound per second is equal to 1.3558179483314 watt when both are expressed in watt-equivalents:
1 ft_lb_s = (1.3558179483314003 W ÷ 1 W) w = 1.3558179483314 w
Each foot-pound per second is defined as 1.3558179483314003 W and each watt as 1 W in this tool, so one ft_lb_s equals 1.3558179483314003 ÷ 1 w = 1.3558179483314 w.
Let d(ft_lb_s) be the numeric value in Foot-pound per Second (ft_lb_s), and d(w) the value in Watt (w). Then:
d(w) = d(ft_lb_s) × (1.3558179483314003 / 1)
Equivalently, divide by how many ft_lb_s fit into one w (watts per w divided by watts per ft_lb_s):
d(w) = d(ft_lb_s) ÷ 0.73756214927727
Or: watt = foot-pound per second ÷ 0.73756214927727
Examples
Example #1: Convert 1 ft_lb_s to watt
1 ft_lb_s = 1 ft_lb_s × (1.3558179483314003/1) w = 1.3558179483 w
1 ft_lb_s = 1 ft_lb_s ÷ 0.73756214927727 = 1.3558179483 w
Intermediate watts: 1.3558179483 W
Example #2: Convert 10 ft_lb_s to watt
10 ft_lb_s = 10 ft_lb_s × (1.3558179483314003/1) w = 13.5581794833 w
10 ft_lb_s = 10 ft_lb_s ÷ 0.73756214927727 = 13.5581794833 w
Intermediate watts: 13.5581794833 W
Summary
To convert Foot-pound per Second to Watt, multiply the value in ft_lb_s by the ratio of watts per ft_lb_s divided by watts per w. Equivalently: value_w = value_ft_lb_s × (1.3558179483314003 / 1). Numerically, 1 ft_lb_s equals 1.3558179483314003 w.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Foot-pounds per Second) and SI / decimal power (watts and prefixes) (Watts). All linear values are mapped through watts first. The numeric factor is 1.355818e+0.
