Formula
Formula
N·m = mN·m × 0.001
Multiply any value in millinewton-metres by 0.001 to obtain the value in newton-metres.
Worked example
Convert 1000 mN·m to N·m.
- 01Start with 1000 mN·m.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 N·m.
Result1000 mN·m = 1 N·m

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