A common review comment is to add units to DT property names. The naming convention is inconsistent unfortunately although there are clear majorities in use already. This makes it hard to remember the exact name preferred, so I'm documenting this to provide an easy point of reference.

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