For exercises which asks for a physical unit the answer field recognizes a variety of unit names which can be prefixed by a set of prefixes. Both the unit names and prefixes can be abbreviated, but abbreviations should only be used in combination with other abbreviations.
For example, one of the prefixes is kilo (k) and one of the units is gram (g). This means that the answer field recognizes the notation kilogram and kg, but will not recognize 'kgram' or 'kilog'.
The following unit tables are supported:
and each unit in these tables can be prefixed by a set of SI prefixes.
