FAQ

What is the conversion factor from gf·cm to mN·m?
1 gf·cm equals 0.0980665 mN·m. To convert, multiply the value in gram-force centimetres by 0.0980665.
How do I convert 1 gf·cm to mN·m?
1 gf·cm = 0.0980665 mN·m. For any value, multiply by 0.0980665.
How do I convert mN·m back to gf·cm?
Divide by the same factor — or equivalently, multiply by 10.19716. So 1 mN·m = 10.1972 gf·cm.
When would I need to convert gram-force centimetre to millinewton-metre?
Torque conversions between gf·cm 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).
