FAQ
What is the conversion factor from gf·cm to lbf·in?
1 gf·cm equals 0.0008679617 lbf·in. To convert, multiply the value in gram-force centimetres by 0.0008679617.
How do I convert 1 gf·cm to lbf·in?
1 gf·cm = 0.000867962 lbf·in. For any value, multiply by 0.0008679617.
How do I convert lbf·in back to gf·cm?
Divide by the same factor — or equivalently, multiply by 1152.125. So 1 lbf·in = 1152.12 gf·cm.
When would I need to convert gram-force centimetre to pound-force inch?
Torque conversions between gf·cm 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).
