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.

Dyne Centimeter [dyn·cm]

Dyne centimeter (dyn·cm) is a unit of torque or moment of force used in the centimeter-gram-second (CGS) system. It represents the torque produced when a force of one dyne is applied at a distance of one centimeter (cm) from a pivot point. The dyne is a small force unit defined as the force needed to accelerate a mass of one gram at one centimeter per second squared.

This unit is commonly used in fields such as physics, material science, and micro-mechanical engineering, where very small forces and precise torque measurements are necessary. For instance, dyn·cm is useful in calibrating delicate instruments, testing the mechanical properties of small samples, or working with microscale devices.

In SI units, 1 dyn·cm is equivalent to 10⁻⁷ newton-meters (N·m). While SI units like the newton-meter have largely replaced CGS units in most scientific and engineering applications, dyne centimeters remain relevant in specialized areas where the CGS system is still applied for convenience or tradition.
