How it works
We use ft-lb = Nm x 0.737562149277.
Exact relationship: 1 Nm = 0.737562149277 ft-lb.
Example: 10 Nm = 7.376 ft-lb.
Notes: Results are rounded in the default view.
Examples
- 10 Nm = 7.376 ft-lb
- 100 Nm = 73.756 ft-lb
- 300 Nm = 221.269 ft-lb
FAQ
What physical quantity do newton-meters and foot-pounds express?
Newton-meters express torque, meaning rotational moment rather than straight-line force or pressure. Foot-pounds express torque in customary engineering contexts and are widely used in mechanical assembly and vehicle service work.
What is the difference between newton-meters and foot-pounds?
Newton-meters and foot-pounds both express torque, but they come from different engineering conventions and are used in different tool, vehicle, and machine ecosystems.
What is the history of the newton-meter?
The newton-meter follows from SI force and distance units and became the standard torque unit in modern metric engineering work.
What is the history of the foot-pound?
Foot-pounds grew from customary force-and-distance engineering practice and remain common in U.S. torque specifications.
Were the newton-meter and foot-pound discovered by a specific person?
The newton-meter is an SI-derived standardized unit rather than a single-person discovery. Foot-pounds emerged from engineering convention and standardization rather than discovery by one person.
Where are newton-meters and foot-pounds used in science and engineering?
Newton-meters are common in fastener torque specs, motors, shafts, drivetrain work, and international engineering documentation. Foot-pounds are common in automotive service manuals, fastener charts, wrench settings, and U.S.-oriented machine maintenance.
Why do torque units matter in calculations?
Torque units affect wrench settings, fastener integrity, shaft loading, machine setup, and maintenance outcomes. Using the wrong torque unit can cause direct hardware damage or safety risk.
Can I trust this for critical calculations?
Use this for convenience and verify against your governing standard, service manual, or controlled engineering document for critical work. Torque values often tie directly to safety and reliability.
