represents a variable with the label var and the corresponding physical quantity "pq".
represents the unlabeled physical quantity "pq".
- Supported physical quantities include both physical and chemical quantities such as "Length", "ElectricCurrent", and "ChemicalPotential", as well as mathematical and financial quantities such as "Angle" and "Money".
- Combinations of physical quantities are also supported, as well as "PhysicalQuantity" entities.
- pq can also be specified using a list of ordered dimension pairs (such as returned by QuantityVariableDimensions), indicating the magnitude of the pq in that dimension.
- Information of a QuantityVariable may include the following properties:
"Identifier" identifier associated with quantity variable "PhysicalQuantity" physical quantity "UnitDimensions" physical dimensions "CanonicalUnit" canonical units
