Inchpounds

Inch-pounds, also known as inch-pounds force, is a unit of torque that is commonly used in the United States to measure the rotational force of a motor or engine. It is defined as the product of the force applied and the distance from the axis of rotation at which the force is applied, measured in inches and pounds respectively.

One inch-pound is the rotational force required to turn a shaft or axle by one inch. It is a unit of angular momentum and is typically used to measure the torque required to turn a gear or other mechanical component. Inch-pounds are often used in the automotive and industrial sectors to specify the torque requirements of engines, transmissions, and other mechanical systems.

Inch-pounds are commonly used in conjunction with other units of measurement, such as horsepower and foot-pounds. For example, a car's engine may be rated in horsepower, but the torque requirements of the transmission may be specified in inch-pounds. This allows for a more precise measurement of the engine's rotational force and the corresponding torque required to turn the transmission.

Inch-pounds are not an SI unit of measurement and are not commonly used outside of the United States. In other parts of the world, the unit of measurement for torque is typically the newton-meter or the foot-pound. Despite this, inch-pounds remain a widely accepted unit of measurement in the automotive and industrial sectors, particularly in the United States.
