Torque is rotational force — the twisting effort that tightens bolts, drives wheels, and powers engines. Different countries use N·m and lb·ft.
Understanding Torque
Torque = Force × Distance from pivot. If you apply 1 N at the end of a 1 m wrench, you produce 1 N·m. In imperial, 1 lb at 1 ft = 1 lb·ft.
Key Conversion
1 N·m = 0.7376 lb·ft. 1 lb·ft = 1.35582 N·m. For quick estimates: multiply N·m by 0.74, or lb·ft by 1.36.
Automotive Torque Values
Lug nuts: 80–120 N·m (60–90 lb·ft). Oil drain plugs: 25–40 N·m (18–30 lb·ft). Always use a torque wrench for critical fasteners.

Frequently Asked Questions
How do I convert Newton-meters to pound-feet?
Multiply N·m by 0.7376. For example, 100 N·m × 0.7376 = 73.76 lb·ft.
What is the difference between torque and force?
Force is a straight-line push/pull (Newtons). Torque is rotational force (Newton-meters), depending on both force and distance from the pivot.
