FAQ
What is the conversion factor from kgf·m to lbf·in?
1 kgf·m equals 86.79617 lbf·in. To convert, multiply the value in kilograms-force metre by 86.79617.
How do I convert 1 kgf·m to lbf·in?
1 kgf·m = 86.7962 lbf·in. For any value, multiply by 86.79617.
How do I convert lbf·in back to kgf·m?
Divide by the same factor — or equivalently, multiply by 0.01152125. So 1 lbf·in = 0.0115212 kgf·m.
When would I need to convert kilogram-force metre to pound-force inch?
Torque conversions between kgf·m and lbf·in 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).
