Foot Pounds to Newton Meters Conversion Table

Quick Answer:

1 foot pound = 1.35582 newton meters. To convert foot pounds to newton meters, multiply the foot pound value by 1.35582.

Foot pounds and newton meters measure torque in automotive, engineering, and mechanical applications.

Detailed Overview: Foot Pounds to Newton Meters

A foot pound (ft-lb) is an imperial torque unit. A newton meter (Nm) is the SI unit of torque. 1 ft-lb = 1.35582 Nm. 1 Nm = 0.737562 ft-lb. Multiply ft-lb by 1.35582 for Nm. Multiply Nm by 0.737562 for ft-lb. Used in engine specs, bolt tightening, and machinery. A 300 ft-lb engine produces 406.75 Nm.

Conversion Reference Table

      1 ft-lb = 1.3558 Nm, 10 ft-lb = 13.5582 Nm, 50 ft-lb = 67.7910 Nm, 100 ft-lb = 135.5818 Nm, 200 ft-lb = 271.1636 Nm, 300 ft-lb = 406.7454 Nm
    

Practical Calculation Example

Convert 180 ft-lb: Nm = 180 × 1.35582 = 244.05 Nm. Reverse: 500 Nm = 500 × 0.737562 = 368.78 ft-lb

Key Takeaways

1 foot pound = 1.35582 newton meters. Multiply ft-lb by 1.35582. Multiply Nm by 0.737562.

THE AUTORANK Editorial Note: When using a torque wrench, always verify whether the scale is in ft-lb or Nm to avoid over-tightening.
