Formula
Formula
mN·m = N·m × 1000
Multiply any value in newton-metres by 1000 to obtain the value in millinewton-metres.
Worked example
Convert 1 N·m to mN·m.
- 01Start with 1 N·m.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 mN·m.
Result1 N·m = 1000 mN·m

FAQ
What is the conversion factor from N·m to mN·m?
1 N·m equals 1000 mN·m. To convert, multiply the value in newton-metres by 1000.
How do I convert 1 N·m to mN·m?
1 N·m = 1000 mN·m. For any value, multiply by 1000.
How do I convert mN·m back to N·m?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mN·m = 0.001 N·m.
When would I need to convert newton-metre to millinewton-metre?
Torque conversions between N·m and mN·m 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).
