Force and Torque
mN·mtokN·m
Convert millinewton-metres (mN·m) to kilonewton-metres (kN·m).
Factor1 mN·m = 1e-6 kN·m
Converter
mN·m
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kN·m
Rendered to 6 significant figures.
Formula
Formula
kN·m = mN·m × 1e-6
Multiply any value in millinewton-metres by 1e-6 to obtain the value in kilonewton-metres.
Worked example
Convert 1.00000e+6 mN·m to kN·m.
- 01Start with 1.00000e+6 mN·m.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 kN·m.
Result1.00000e+6 mN·m = 1 kN·m

FAQ
What is the conversion factor from mN·m to kN·m?
1 mN·m equals 1e-6 kN·m. To convert, multiply the value in millinewton-metres by 1e-6.
How do I convert 1 mN·m to kN·m?
1 mN·m = 1e-6 kN·m. For any value, multiply by 1e-6.
How do I convert kN·m back to mN·m?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 kN·m = 1.00000e+6 mN·m.
When would I need to convert millinewton-metre to kilonewton-metre?
Torque conversions between mN·m and kN·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).
