There are 6 base units that are supported:
s
for second [time]m
for meter [distance]g
for gram [mass]A
for ampere [current]K
for kelvin [temperature]cd
for candela [light intensity]We decided not to support mol for mole because it is already a number. There are also some composite/other units we decided to support for conveniency:
rad
for radian and deg
for degree [angle]sr
for steradian and deg2
for square degree [angle but 3d]Hz
for hertz [frequency]N
for newton [force]Pa
for pascal [pressure]J
for joule [energy/work]W
for watt [power]V
for volt [voltage]F
for farad [capacitance]Ω
/ohm
for ohm [resistance]Hz
for hertz [frequency]Hz
for hertz [frequency]
