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
The kilogram-force (kgf or kg), or kilopond (kp, from Latin "pondus" meaning "weight"), is a gravitational metric unit of force. It is equal to the magnitude of the force exerted on one kilogram of mass in a gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). Therefore, one kilogram-force is by definition equal to . Similarly, a gram-force is , and a milligram-force is . One kilogram-force is approximately 2.204622 pound-force.
