Torque
Convert N·m, lb-ft, kg-cm, oz-in
What is it?
Torque (or moment of force) is a physical quantity measuring the rotational force applied around an axis. It is an essential measurement in automotive mechanics, engineering, and industrial maintenance. Torque determines an engine's ability to deliver power, the tightening force of bolts, and the operation of transmission systems.

Practical Applications
Automotive mechanics consult torque specifications for cylinder head bolts, wheel nuts, and oil pan screws. Mechanical design engineers size motors and gearboxes in Nm. Industrial maintenance technicians verify torque on critical assemblies. In electronics, oz-in is used for small motors and servos.
Unit Guide
Nm (Newton-meter)
SI unit of torque. Product of a one Newton force applied at a one-meter lever arm. International engineering standard.
lb-ft (Foot-pound)
Imperial torque unit widely used in North America, especially in automotive and aerospace industries.
kg-cm (Kilogram-centimeter)
Historical metric unit still used for servo motor specifications and in robotics.
oz-in (Ounce-inch)
Small torque unit used in electronics, for micro-motors and precision instruments.
Practical Tips
- 1
Wheel lug nut torque varies by vehicle: 80-120 Nm for cars, 140-200 Nm for SUVs.
- 2
Always use a calibrated torque wrench for critical fastenings.
- 3
A typical compact car engine produces about 150-250 Nm of peak torque.
- 4
Formula 1 engines deliver about 350 Nm at over 10,000 rpm.
