FAQ

What is the conversion factor from kgf·m to N·m?
1 kgf·m equals 9.80665 N·m. To convert, multiply the value in kilograms-force metre by 9.80665.
How do I convert 1 kgf·m to N·m?
1 kgf·m = 9.80665 N·m. For any value, multiply by 9.80665.
How do I convert N·m back to kgf·m?
Divide by the same factor — or equivalently, multiply by 0.1019716. So 1 N·m = 0.101972 kgf·m.
When would I need to convert kilogram-force metre to newton-metre?
Torque conversions between kgf·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?
Yes. Both kgf·m and N·m are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
