Force gauge
Test units of force measurements are most commonly newtons or pounds. The peak force is the most common result in force testing applications. It is used to determine if a part is good or not. Some examples of force measurement: door latch, quality of spring, wire testing, strength ... but more complicated tests can be performed like peeling, friction, texture.
English Engineering units
In English Engineering units, the pound mass and the pound force are distinct base units, and Newton's Second Law of Motion takes the form "F" = "ma"/"g", where "g" = 32.174 lb·ft/(lbf·s).
