Metric Horsepower to Foot-pounds per Second Converter

To convert a measurement in metric horsepower to foot-pounds per second, multiply the value by 542.476039. The conversion factor comes from the relationship between both units and the watt.

For example, to convert 5 PS to foot-pounds per second: 5 × 542.476039 = 2,712.3802 ft·lb/s.

Metric horsepower (PS or cv) is a unit of power equal to exactly 735.49875 watts, slightly less than mechanical horsepower. Defined in continental Europe, metric horsepower (from the German 'Pferdestärke', PS) is the traditional unit for car engine power in Europe and Japan, where figures are often quoted in PS.

Common uses of metric horsepower include: European and Japanese car engine ratings; Motorcycle power specifications; Comparing PS to hp and kW; Automotive marketing figures.

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 PS = 542.476039 ft·lb/s 5 PS = 2,712.3802 ft·lb/s 10 PS = 5,424.7604 ft·lb/s 50 PS = 27,123.8019 ft·lb/s 100 PS = 54,247.6039 ft·lb/s
