MECHANICAL UNIT CONVERTER
Engineering Torque N·m / lbf·ft / lbf·in Converter
Convert torque between newton metres, pound-force feet and pound-force inches while keeping the distinction between force, mass and torque explicit.
Results
Newton metres100 N·m
Pound-force feet73.75621 lbf·ft
Pound-force inches885.07458 lbf·in
Engineering method
Uses exact/standard force and length relationships derived from SI definitions and standard gravity conventions for pound-force.
Model / conversion relationship
1 lbf·ft ≈ 1.3558179483 N·m; 1 lbf·in ≈ 0.1129848290 N·m.
