Polymorphic Units in LabVIEW

Using units gives you an additional level of consistency checking when evaluating expressions and formulas, also known as dimensional analysis. With LabVIEW, you do not have to worry about conversions between systems of units, because LabVIEW handles unit conversion when it displays or enters data.

The LabVIEW built-in functions, such as Add and Multiply, are polymorphic with respect to units, so they automatically handle different units. But in order to build a subVI with the same polymorphic unit capability, you must use polymorphic units.
