Watts to Foot-pounds per Second Converter

To convert a measurement in watts to foot-pounds per second, multiply the value by 0.737562149277. The conversion factor comes from the relationship between both units and the watt.

For example, to convert 5 W to foot-pounds per second: 5 × 0.737562149277 = 3.687811 ft·lb/s.

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.

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.

Here are some common values converted:

1 W = 0.737562149277 ft·lb/s 5 W = 3.687811 ft·lb/s 10 W = 7.375621 ft·lb/s 50 W = 36.878107 ft·lb/s 100 W = 73.756215 ft·lb/s
