FAQ

What is the conversion factor from N·m to lbf·ft?
1 N·m equals 0.7375621 lbf·ft. To convert, multiply the value in newton-metres by 0.7375621.
How do I convert 1 N·m to lbf·ft?
1 N·m = 0.737562 lbf·ft. For any value, multiply by 0.7375621.
How do I convert lbf·ft back to N·m?
Divide by the same factor — or equivalently, multiply by 1.355818. So 1 lbf·ft = 1.35582 N·m.
When would I need to convert newton-metre to pound-force foot?
Torque conversions between N·m and lbf·ft are needed in fastener specification, mechanical equipment design, drivetrain analysis and lifting/rigging calculations. Newton-metre (N·m) is the SI standard; lbf·ft and lbf·in dominate US fastener and machinery datasheets; kgf·m appears in legacy metric documentation. Display symbol is N·m — never the abbreviation "nm", which denotes nanometre.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
