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).
Kip (unit)
The name comes from combining the words "kilo" and "pound"; it is occasionally called a "kilopound". Its symbol is kip, or less frequently, klb. When it is necessary to clearly distinguish it as a unit of force rather than mass, it is sometimes called the "kip-force" (symbol kipf or klbf).
Note that the symbol kp usually stands for a different unit of force, the "kilopond" or kilogram-force used primarily in Europe prior to the introduction of SI units.
