You typically use instances of NSUnitPressure to represent specific quantities of pressure using the NSMeasurement class.
あなたは概してNSUnitPressureのインスタンスを使用して、NSMeasurementクラスを使っている圧力の具体的な量を表します。
Pressure
Pressure is the normal force over a surface.
圧力は、ある面の全体にわたる垂直力です。
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 base unit as newtonsPerMetersSquared and provides the following units, which UnitConverterLinear converters initialize with the given coefficients:
