FAQ
What is the conversion factor from ozf·in to gf·cm?
1 ozf·in equals 72.00779 gf·cm. To convert, multiply the value in ounce-force inches by 72.00779.
How do I convert 1 ozf·in to gf·cm?
1 ozf·in = 72.0078 gf·cm. For any value, multiply by 72.00779.
How do I convert gf·cm back to ozf·in?
Divide by the same factor — or equivalently, multiply by 0.01388739. So 1 gf·cm = 0.0138874 ozf·in.
When would I need to convert ounce-force inch to gram-force centimetre?
Torque conversions between ozf·in 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).
