Gram-Force Centimeter [gf·cm]

Gram-force centimeter (gf·cm) is a unit of torque or moment of force used to measure small rotational forces, commonly applied in precision engineering, watchmaking, electronics, and small mechanical assemblies. It represents the torque generated when a force of one gram-force (gf) is applied at a distance of one centimeter (cm) from a pivot point.

This unit is especially useful for situations requiring accurate control of low-level torque, such as tightening tiny screws, calibrating sensitive instruments, or testing miniature mechanical components. The gram-force centimeter provides a practical and intuitive scale for these tasks, bridging the gap between very fine torque measurements and larger units like pound-force foot or newton-meter.

Although the SI unit of torque is the newton-meter (N·m), the gf·cm remains valuable in applications where imperial or metric small-force units are more convenient. To convert, 1 gf·cm is approximately 9.80665 × 10⁻⁵ N·m.

Using gram-force centimeters helps ensure the precision and reliability of devices by preventing damage due to improper torque application, making it a favored unit in many delicate engineering fields.

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.
