Foot-pounds per Second to Watts Converter

To convert a measurement in foot-pounds per second to watts, multiply the value by 1.355818. The conversion factor comes from the relationship between both units and the watt.

For example, to convert 5 ft·lb/s to watts: 5 × 1.355818 = 6.77909 W.

A foot-pound per second is an imperial unit of power equal to about 1.356 watts, representing one foot-pound of work performed each second. Rooted in imperial mechanics, the foot-pound per second is the basis from which horsepower was defined — 550 ft·lb/s equals one mechanical horsepower.

Common uses of foot-pounds per second include: Mechanical engineering in imperial units; Deriving horsepower from work rate; Physics work-and-power problems; Legacy machinery specifications.

A watt is the SI derived unit of power, equal to one joule of energy per second (1 J/s). Named after Scottish engineer James Watt, whose steam-engine improvements powered the Industrial Revolution. The watt became the SI unit of power in 1960 and now measures everything from light bulbs to power plants.

Common uses of watts include: Light bulb and appliance ratings; Electronic device power consumption; Audio amplifier output; Scientific and electrical calculations.

Here are some common values converted:

1 ft·lb/s = 1.355818 W 5 ft·lb/s = 6.77909 W 10 ft·lb/s = 13.558179 W 50 ft·lb/s = 67.790897 W 100 ft·lb/s = 135.581795 W
