Horsepower (hp) to Foot-Pound per Second (ft-lb/s) Conversion
The conversion from horsepower (hp) to foot-pound per second (ft-lb/s) is an important calculation in mechanical engineering and power system design. Horsepower is a traditional power unit widely used in automotive, marine and industrial equipment, while foot-pound per second is another commonly used power representation. Accurate unit conversion is crucial for equipment selection, performance evaluation and engineering design.
This tool provides professional hp to ft-lb/s conversion functionality, supporting real-time calculation and precise conversion, suitable for the daily work needs of mechanical engineers, automotive technicians and industrial design professionals.
Conversion Formula
The conversion between horsepower (hp) and foot-pound per second (ft-lb/s) is based on the definition of horsepower:
Basic Formula:
- 1 hp = 550 ft-lb/s
- 1 ft-lb/s = 0.001818 hp (1/550 hp)
Conversion Formulas:
- hp to ft-lb/s: ft-lb/s = hp × 550
- ft-lb/s to hp: hp = ft-lb/s ÷ 550
