What is Torque?
Torque is a measure of the rotational force applied to an object. It's the twisting force that causes rotation around an axis, fulcrum, or pivot. Torque is calculated by multiplying the force applied by the distance from the pivot point.
The SI unit for torque is the Newton-meter (N⋅m), but various other units are used depending on the region and application. In automotive contexts, pound-feet (lb⋅ft) is commonly used in the United States, while Newton-meters are standard in most other countries.
Common Applications of Torque
Automotive Engineering
Engine torque specifications, wheel lug nut tightening, and cylinder head bolt torque
Mechanical Engineering
Fastener specifications, assembly procedures, and quality control
Manufacturing
Torque wrenches, assembly line specifications, and quality assurance testing
Aerospace
Aircraft assembly, critical bolt specifications, and maintenance procedures
Understanding Torque Units
Newton-meters (N⋅m)
The SI standard unit for torque. One Newton-meter is the torque resulting from a force of one Newton applied perpendicularly to a moment arm which is one meter long.
Pound-feet (lb⋅ft)
Commonly used in the United States for automotive and mechanical applications. One pound-foot equals approximately 1.356 Newton-meters.
Pound-inches (lb⋅in)
Used for smaller fasteners and precision applications. There are 12 pound-inches in one pound-foot. One pound-inch equals approximately 0.113 Newton-meters.
Kilogram-force meters (kgf⋅m)
A metric unit based on gravitational force. While not an SI unit, it's still used in some regions. One kgf⋅m equals approximately 9.807 Newton-meters.
Frequently Asked Questions
What's the difference between torque and horsepower?
Torque is rotational force, while horsepower is the rate at which work is done. Torque measures the twisting force, whereas horsepower measures how quickly that force can be applied over time. They are related: Horsepower = (Torque × RPM) / 5,252.
Why do some torque wrenches use lb⋅ft instead of N⋅m?
Regional preferences vary. The United States primarily uses imperial units (lb⋅ft), while most other countries use metric units (N⋅m). Many modern torque wrenches feature dual scales or allow switching between units.
