FAQ
What is the conversion factor from ozf·in to mN·m?
1 ozf·in equals 7.061552 mN·m. To convert, multiply the value in ounce-force inches by 7.061552.
How do I convert 1 ozf·in to mN·m?
1 ozf·in = 7.06155 mN·m. For any value, multiply by 7.061552.
How do I convert mN·m back to ozf·in?
Divide by the same factor — or equivalently, multiply by 0.1416119. So 1 mN·m = 0.141612 ozf·in.
When would I need to convert ounce-force inch to millinewton-metre?
Torque conversions between ozf·in and mN·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?
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).
