Units

Frinj keeps tracks of units, 2 kinds of prefixes and fundamental units.

All fjv's are always normalised to fundamental units to make it possible to add, multiply and convert them.

Prefixes

Prefixes are units-less factors that are multiplied to the units. There are 2 kinds of prefixes, normal and standalone. A standalone prefix can be used as a unit where the normal ones alway prefix a unit name.

• :cm is prefix c + unit m. Being 1/100 * m

• :kilo is a standalone prefix of value 1000

• :kilobit is 1000 of unit bits

Note that only one prefix can by used before a unit name; :ccm is not centi-centi-meter, but the unit called ccm. (fj :centi :cm) is a centi-cent-meter

Units

Most of the units come in both singular and plural form. So :meter and :meters is the same.
