dimensions


Explanation:
2.1 UNITS AND DIMENSIONS

A measured or counted quantity has a numerical value (2.47) and a unit (whatever there are 2.47 of). It is useful in most engineering calculations -- and essential in many -- to write both the value and the unit of each quantity appearing in an equation:

2 feet, 1/3 second, 4.29 miles, 6 tomatoes, ...

A dimension is a property that can be measured, such as length, time, mass, or temperature, or calculated by multiplying or dividing other dimensions, such as length/time (velocity), length3 (volume), or mass/length3 (density). Measurable units (as opposed to countable units) are specific values of dimensions that have been defined by convention, custom, or law, such as grams for mass, seconds for time, centimeters or feet for length, and so on.

Units can be treated like algebraic variables when quantities are added, subtracted, multiplied, or divided. The numerical values of two quantities may be added or subtracted only if the units are the same:

--------

The dimension of a physical quantity can be expressed as a product of the basic physical dimensions such as length, mass and time, each raised to a rational power. The dimension of a physical quantity is more fundamental than some scale unit used to express the amount of that physical quantity. For example, mass is a dimension, while the kilogram is a particular scale unit chosen to express a quantity of mass. Except for natural units, the choice of scale is cultural and arbitrary - https://en.wikipedia.org/wiki/Dimensional_analysis#Definitio...
