1Standard Unit Suffixes for Property names
2
3Properties which have a unit of measure are recommended to have a unit
4suffix appended to the property name. The list below contains the
5recommended suffixes. Other variations exist in bindings, but should not
6be used in new bindings or added here. The inconsistency in the unit
7prefixes is due to selecting the most commonly used variants.
8
9It is also recommended to use the units listed here and not add additional
10unit prefixes.
