Kilowatt (kW) to Foot-Pound per Second (ft-lb/s) Conversion

The conversion from kilowatt (kW) to foot-pound per second (ft-lb/s) is an important calculation in mechanical engineering and power system design. This tool provides precise kW to ft-lb/s conversion functionality, supporting accurate conversion between US engineering units and international units. Widely used in mechanical equipment power calculations, power transmission system design, hydraulic system engineering and other professional fields, helping engineers quickly complete power unit conversions.

Conversion Formula

The conversion between kilowatt (kW) and foot-pound per second (ft-lb/s) is based on the relationship between metric and imperial power units:

Basic Formula:

  • 1 kW = 737.56 ft-lb/s
  • 1 ft-lb/s = 0.001356 kW

Conversion Formulas:

  • kW to ft-lb/s: ft-lb/s = kW × 737.56
  • ft-lb/s to kW: kW = ft-lb/s ÷ 737.56

Application Examples

Industrial Motors

  • Electric Motor: 10 kW = 7,375.6 ft-lb/s
  • Pump Motor: 5 kW = 3,687.8 ft-lb/s
  • Compressor Motor: 15 kW = 11,063.4 ft-lb/s
  • Fan Motor: 3 kW = 2,212.7 ft-lb/s

Hydraulic Systems

  • Hydraulic Pump: 20 kW = 14,751.2 ft-lb/s
  • Hydraulic Motor: 8 kW = 5,900.5 ft-lb/s
  • Power Unit: 25 kW = 18,439.0 ft-lb/s
  • Servo System: 2 kW = 1,475.1 ft-lb/s

Power Transmission

  • Gearbox: 50 kW = 36,878.0 ft-lb/s
  • Belt Drive: 12 kW = 8,850.7 ft-lb/s
  • Chain Drive: 18 kW = 13,276.1 ft-lb/s
  • Coupling: 30 kW = 22,126.8 ft-lb/s

Manufacturing Equipment

  • CNC Machine: 7.5 kW = 5,531.7 ft-lb/s
  • Conveyor System: 4 kW = 2,950.2 ft-lb/s
  • Mixer: 22 kW = 16,226.3 ft-lb/s
  • Press Machine: 35 kW = 25,814.6 ft-lb/s

Usage Recommendations

  1. Engineering Design: Convert between metric and imperial power units
  2. Equipment Specification: Standardize power ratings across different systems
  3. Performance Analysis: Compare equipment performance in different unit systems
  4. Technical Documentation: Ensure consistency in international projects
  5. System Integration: Match components with different power unit specifications
