Other units of pressure, such as pounds per square inch (lbf/in) and bar, are also in common use. The CGS unit of pressure is the barye (Ba), equal to 1 dyn·cm, or 0.1 Pa. Pressure is sometimes expressed in grams-force or kilograms-force per square centimetre ("g/cm " or "kg/cm ") and the like without properly identifying the force units. But using the names kilogram, gram, kilogram-force, or gram-force (or their symbols) as units of force is deprecated in SI. The technical atmosphere (symbol: at) is 1 kgf/cm (98.0665 kPa, or 14.223 psi).
