mention the requisites of a unit
Asked by | 3rd Aug, 2008, 11:17: AM
The unit should be consistent.
For most quantities a unit is absolutely necessary to communicate values of that physical quantity. For example, conveying to someone a particular length without using some sort of unit is impossible, because a length cannot be described without a reference used to make sense of the value given.
Treat units like variables. Only add like terms.
Some units have special names, however these should be treated like their equivalents. For example, one newton (N) is equivalent to one kg·m/s².
