PD.Units. Pressure

Provides tools to convert between different pressure units.

Use static methods for arbitrary conversions and instance methods when converting to and/or from a specific unit multiple times. The available pressure unit types are: PD.Units.PASCAL, PD.Units.KILOPASCAL, PD.Units.MILLIMETERS_MERCURY, PD.Units.INCHES_MERCURY, PD.Units.POUNDS_PER_SQUARE_INCH, PD.Units.ATMOSPHERES and PD.Units.BAR.

new Pressure( [units])

Creates a new pressure converter.

Parameters:
Name Type Argument Description
units number <optional>

The units type identifier, defaults to PD.Units.PASCAL.

Members
