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.
Kilogram-force
It is also used for tension of bicycle spokes, for informal references to pressure in kilograms per square centimeter (1 kp/cm) which is the technical atmosphere (at) and very close to 1 bar and the standard atmosphere (atm), for the draw weight of bows in archery, and to define the "metric horsepower" (PS) as 75 metre-kiloponds per second. In addition, kilograms force is the standard unit used for Vickers hardness testing.
The tonne-force, metric ton-force, megagram-force, and megapond (Mp) are each 1000 kilograms-force.
