Newton-meters to Pound-feet (ft-lb) (N·m to lbf·ft)
Convert newton-meters to pound-feet (ft-lb): 1 N·m = 0.737562 lbf·ft. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 N·m = 0.737562 lbf·ft
pound-feet (ft-lb) = newton-meters × 0.7375621493 — reverse: newton-meters = pound-feet (ft-lb) × 1.355817948
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 = 3.68781 lbf·ft
- 12.5 N·m = 9.21953 lbf·ft
- 100 N·m = 73.7562 lbf·ft
