kN·mtomN·m

Convert kilonewton-metres (kN·m) to millinewton-metres (mN·m).

Factor1 kN·m = 1000000 mN·m

Converter

kN·m

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1.00000e+6mN·m

Rendered to 6 significant figures.

Formula

Formula
mN·m = kN·m × 1000000

Multiply any value in kilonewton-metres by 1000000 to obtain the value in millinewton-metres.

Worked example

Convert 1 kN·m to mN·m.

  1. 01Start with 1 kN·m.
  2. 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 mN·m.
Result1 kN·m = 1.00000e+6 mN·m

FAQ

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