How the Nm to ft-lb Calculator Works
Both Newton-meters (Nm) and foot-pounds (ft-lb) are torque units. This converter uses high-precision constants so your torque specs match workshop manuals, service data, and engineering references.
- ft-lb = Nm × 0.7375621493
- Nm = ft-lb × 1.3558179483
- Conversions update live as you type — no submit button.
- Use the Decimals control to fine-tune precision without forced trailing zeros.
How do I convert Nm to ft-lb?
Multiply the torque in Newton-meters by 0.7375621493. Example: 200 Nm × 0.7375621493 ≈ 147.512 ft-lb. Our tool does this instantly for you with adjustable precision.
How do I convert ft-lb to Nm?
Multiply the torque in foot-pounds by 1.3558179483. Example: 70 ft-lb × 1.3558179483 ≈ 94.907 Nm. This is useful when manuals list specs in ft-lb but your torque wrench is in Nm (or the other way around).
Are Nm and ft-lb interchangeable for torque?
They describe the same physical concept (a force at a distance) using different unit systems. Always convert rather than “rounding by feeling” — incorrect torque can damage fasteners, cylinder heads, wheel lugs, or critical components.
What is 200 Nm in ft-lb? What is 70 ft-lb in Nm?
200 Nm ≈ 147.512 ft-lb and 70 ft-lb ≈ 94.907 Nm using the exact constants built into this calculator. These are common values for wheel nuts and engine components.
This tool is for quick reference and educational use. Always follow the official torque specifications from your manufacturer, service manual, or engineering documentation.
