Conversion Formula
ft⋅lbf/s = erg/s × 7.375621493e-8
About Ergs per Second
An erg per second (erg/s) is the CGS unit of power - exactly 10⁻⁷ W. Despite SI adoption, erg/s persists in astrophysics: the Sun's total luminosity is 3.828 × 10³³ erg/s; a peak supernova radiates ~10⁴³ erg/s - more power than the Sun emits over its 10-billion-year lifetime. X-ray binaries, active galactic nuclei, and neutron star accretion rates are catalogued in erg/s across decades of archival literature. 1 erg/s = 10⁻⁷ W.
About Foot-Pounds per Second
One foot-pound per second (ft·lbf/s) ≈ 1.3558 W - the natural power unit in the foot-pound-second (FPS) system. Since 1 mechanical horsepower = exactly 550 ft·lbf/s, the conversion 1 ft·lbf/s = 1/550 hp is exact. Used in FPS structural and fluid dynamics: beam deflection power, pump and turbine output, and ballistic energy-transfer calculations. 19th-century American industry rated waterwheel output in ft·lbf/s before horsepower standardisation. 1 ft·lbf/s = 1.35582 W.
