About both units

From

Foot-Pound per Second

ft·lbf/s

Foot-pound per second equals 1.356 watts. Historical US mechanical-engineering unit, now largely replaced by watts or hp. Still appears in older engineering texts.

Real-world: Largely historical; modern specs use W or hp.

Volt-Ampere

The volt-ampere equals one watt for purely resistive loads, but differs from watts for inductive or capacitive AC loads. Used for transformer, UPS and generator sizing — which must handle apparent power, not just real power.

Real-world: Home UPS: 600–1500 VA. Transformer: kVA ratings. Motor power factor typically 0.8 — 1 kW motor = 1.25 kVA.

Tips & common mistakes

Quick tips

1 ft·lbf/s = 1.356 W.
550 ft·lbf/s = 1 mechanical hp.
Rarely needed today outside archival references.

Avoid these

Confusing ft·lbf/s (power) with ft·lbf (torque or work).
Using in modern specifications — prefer W or kW.
Mixing with foot-pound (energy) in same calculation.
