About this converter
Moment of force, also called torque, measures a force applied at a perpendicular distance from an axis. Newton meter (N·m) is the SI unit, and 1 pound-force foot equals 1.355817948 N·m.
This converter supports SI, metric-force, ton-force, pound-force, and poundal-based moment units. Mechanical engineers, structural engineers, automotive technicians, machine designers, and physics students use these conversions for fasteners, beams, shafts, levers, and rotational equilibrium checks.

How to Convert N·m to lbf·ft
Newton meters to pound-force feet
For example, 120 N·m / 1.355817948 = 88.5075 lbf·ft.
Pound-force feet to newton meters
For example, 75 lbf·ft x 1.355817948 = 101.686 N·m.
When You Need to Convert Moment of Force
Automotive manuals may list fastener torque in lbf·ft while imported tools or service documents use N·m. A 100 lbf·ft wheel torque equals 135.582 N·m, so technicians can set the correct wrench value.
Structural engineers often work with bending moments in kN·m, while smaller component checks may use N·m. A beam moment of 12 kN·m equals 12,000 N·m before comparing it with connection or bracket capacity.
Machine designers use moment units when calculating torque from force and lever arm. A 200 N force applied 0.5 m from a shaft creates 100 N·m, which is 73.7562 lbf·ft for imperial documentation.
