What is Nm and lb-ft?
Torque is measured in different units depending on the measurement system.
- Newton-meter (Nm) → Metric system
- Pound-foot (lb-ft) → Imperial system
Both represent rotational force but use different units of measurement.

Nm to lb-ft Conversion Formula
1 Nm = 0.737562 lb-ft
So the formula is:
lb-ft = Nm × 0.737562
How to Convert Nm to lb-ft (Step-by-Step)
- Take torque value in Nm
- Multiply by 0.737562
- Result is in lb-ft
Example:
50 Nm × 0.737562 = 36.88 lb-ft
