Kilogram-Force Centimeter [kgf·cm]

Kilogram-force centimeter (kgf·cm) is a unit of torque or moment of force that measures rotational force by applying a force of one kilogram-force (kgf) at a distance of one centimeter (cm) from a pivot point. This unit is widely used in mechanical engineering, instrument calibration, and small machinery design, where moderate torque values need to be measured with precision.

The kilogram-force (kgf) itself is a unit of force based on the gravitational force exerted by one kilogram of mass, making kgf·cm intuitive for practical applications involving mechanical components and assemblies. It is especially common in industries dealing with small to medium-sized torques, such as automotive, robotics, and manufacturing sectors.

Though the newton-meter (N·m) is the official SI unit of torque, kgf·cm remains popular in many settings due to historical use and convenience when working with forces in kilograms and distances in centimeters. For conversion, 1 kgf·cm is approximately 0.09807 newton-meters.

Using kilogram-force centimeters helps engineers and technicians accurately control and specify torque levels, preventing damage and ensuring optimal performance of mechanical systems.

Pound-Force Foot [lbf·ft]

Pound-force foot (lbf·ft) is a unit of torque or moment of force commonly used in the United States and other countries that employ the imperial system. It measures the rotational force applied at a distance of one foot from a pivot point. Specifically, it represents the torque produced when a force of one pound-force (lbf) is applied perpendicular to a lever arm that is one foot (ft) long.

This unit is widely used in mechanical engineering, automotive industries, and machinery design to quantify twisting forces that cause rotation. For example, when tightening bolts, the torque applied is often specified in lbf·ft to ensure proper fastening without over-tightening. Similarly, engine torque ratings are frequently expressed in pound-force feet, indicating the rotational force an engine can generate.

While the SI unit of torque is the newton-meter (N·m), lbf·ft remains popular in practical applications within the imperial system due to familiarity and ease of use. To convert, 1 lbf·ft equals approximately 1.356 N·m.
