class UnitPressureOverview
You typically use instances of UnitPressure to represent specific quantities of pressure using the NSMeasurement class.
Pressure
Pressure is the normal force over a surface. The SI unit for pressure is the pascal (Pa), which is derived as one newton of force over one square meter (1 Pa = 1 N / 1 m2).
The UnitPressure class defines its baseUnit() as newtonsPerMetersSquared and provides the following units, which UnitConverterLinear converters initialize with the given coefficients:
