Kind of Quantity

A KindOfQuantity represents the general notion of a quantity, such as: a length, mass, speed, etc. This can be contrasted with more specific quantity definitions, like: my height, your weight, etc.

KindOfQuantity objects are defined (and identified) by a name and a term (a short name). For example, this code creates a new context with the base kinds of quantity Length and Time

from QV import *

context = Context( ("Length","L"), ("Time","T") )
Length, Time = context.base_quantities

The algebraic rules of quantity calculus are defined for KindOfQuantity objects (see, context).

class KindOfQuantity(name, symbol)

A type of quantity like mass, length, etc.

KindOfQuantity objects can be multiplied and divided. Declaring a ratio and simplifying a ratio is also supported.
