Converting torque values from ft-lbs to Nm (foot-pounds to Newton-meters) and Nm to ft-lbs is a daily requirement for mechanics, engineers, and anyone working with international specifications. This guide provides the official conversion factors and a quick-reference chart.

The Official Conversion Factors

Memorize these two numbers to handle any torque conversion with ease.

• 1 Pound-Foot (ft-lb) = 1.35582 Newton-meters (Nm)

• 1 Newton-meter (Nm) = 0.73756 Pound-Feet (ft-lbs)

How to Convert Ft-Lbs to Nm

To convert from foot-pounds to Newton-meters, you multiply by 1.35582.

• Formula: Nm = ft-lbs × 1.35582

• Example: Convert 100 ft-lbs to Nm.
  100 ft-lbs × 1.35582 = 135.582 Nm

How to Convert Nm to Ft-Lbs

To convert from Newton-meters to foot-pounds, you multiply by 0.73756 (or divide by 1.35582 for more precision).

• Formula: ft-lbs = Nm × 0.73756

• Example: Convert 50 Nm to ft-lbs.
  50 Nm × 0.73756 = 36.878 ft-lbs
