The pound of force or pound-force (symbol: lbf, [1] sometimes lb f, [2]) is a unit of force used in some systems of measurement, including English Engineering units [a] and the foot–pound–second system.

2015年8月25日 · In the English system, the force unit is the pound-force ($lbf$) and is defined as the force required to accelerate a mass of $32.174\cdot lbm$ (1 slug) at a rate of $1\cdot\frac{ft}{s^2}$. That is...

The pound-force, or simply pound (abbreviations: lb, lb f, or lbf), is a unit of force. The pound-force is about equal to the gravitational force applied on a mass of one pound on the surface of Earth.

2013年12月23日 · Explanation of pounds in US system of units, and how to use in calculations. Difference between Pound-Force and Pound-Mass In the SI (metric) system of units, kilograms are used for mass, and newtons for weight.

“Lbf” refers to the gravitational force placed by a matter on the Earth’s surface, while “lb” deals with the measurement of force. A pound force equals the product of 1 pound and the gravitational field. “Lb” and “lbf” are basically similar with each other since they both involve the same force.

Lbf stands for pound-force, which is a unit of force commonly used in engineering and physics. It represents the force exerted by a one-pound mass under standard gravity conditions. On the other hand, lbs stands for pounds, which is a unit of weight used in everyday life.

2023年6月12日 · In the U.S., it is customary to specify the trigger pull force in pound-force, symbol lbf.NOTE Pound-force lbf is sometimes referred to as pound lb where the context refers to force rather than mass.
