Pound-inches (in-lb) to Newton-meters (lbf·in to N·m)
Convert pound-inches (in-lb) to newton-meters: 1 lbf·in = 0.112985 N·m. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 lbf·in = 0.112985 N·m
newton-meters = pound-inches (in-lb) × 0.112984829 — reverse: pound-inches (in-lb) = newton-meters × 8.850745791
The factor is derived from the SI definitions of both units (base unit: Nm) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 5 lbf·in = 0.564924 N·m
- 12.5 lbf·in = 1.41231 N·m
- 100 lbf·in = 11.2985 N·m

FAQ
How many newton-meters are in one pound-inch?
1 lbf·in = 0.112985 N·m. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.
What is the formula to convert pound-inches (in-lb) to newton-meters?
Multiply the value in pound-inches (in-lb) by 0.112984829: newton-meters = pound-inches (in-lb) × 0.112984829. For example, 5 lbf·in = 0.564924 N·m.
How do I convert newton-meters back to pound-inches (in-lb)?
Multiply by the inverse factor 8.850745791 (pound-inches (in-lb) = newton-meters × 8.850745791), or use the newton-meters-to-pound-inches (in-lb) page.
