FAQ
What is the conversion factor from lbf·ft to gf·cm?
1 lbf·ft equals 13825.5 gf·cm. To convert, multiply the value in pound-force feet by 13825.5.
How do I convert 1 lbf·ft to gf·cm?
1 lbf·ft = 13825.5 gf·cm. For any value, multiply by 13825.5.
How do I convert gf·cm back to lbf·ft?
Divide by the same factor — or equivalently, multiply by 7.233014e-5. So 1 gf·cm = 7.23301e-5 lbf·ft.
When would I need to convert pound-force foot to gram-force centimetre?
Torque conversions between lbf·ft and gf·cm 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).
