While units in Bitcoin usually follow the Standard Metric Notation system, this page lists the most commonly-used units. These can be expressed in any number of ways, from using some form of the prefix to an abbreviation of both the prefix and adding Bitcoin. Bitcoin as a unit of account is commonly written without capitalization, but since it is not a genericized term yet and refers to one specific type of crypto-currency, capitalization is left as an exercise for the reader.
