Newton-meters to Pound-inches (in-lb) (N·m to lbf·in)
Convert newton-meters to pound-inches (in-lb): 1 N·m = 8.85075 lbf·in. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 N·m = 8.85075 lbf·in
pound-inches (in-lb) = newton-meters × 8.850745791 — reverse: newton-meters = pound-inches (in-lb) × 0.112984829
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 N·m = 44.2537 lbf·in
- 12.5 N·m = 110.634 lbf·in
- 100 N·m = 885.075 lbf·in
