Pressure measurement
Many other hybrid units are used such as mmHg/cm or grams-force/cm (sometimes as kg/cm without properly identifying the force units). Using the names kilogram, gram, kilogram-force, or gram-force (or their symbols) as a unit of force is prohibited in SI; the unit of force in SI is the newton (N).
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.
