How It Works

Torque Converter

Conversion Factors from Newton-Meters

  • Foot-Pounds: N·m × 0.737562
  • Inch-Pounds: N·m × 8.85075
  • Kilogram-Force Meters: N·m / 9.80665

    • Worked Example

    Convert 100 N·m to foot-pounds, inch-pounds, and kgf·m.

    value = 100
    1. 01Foot-Pounds = 100 × 0.737562 = 73.7562 ft·lbf
    2. 02Inch-Pounds = 100 × 8.85075 = 885.075 in·lbf
    3. 03kgf·m = 100 / 9.80665 = 10.1972 kgf·m
