convert(tu1, tu2, pcontext \\ %{})
Convert units, for example
iex> import Exun.Unit
iex> "120[Km/h]" |> convert("m/s")
"33.333333333333336[m/s]"

convert_ast(arg1, arg2, pcontext \\ %{})
Convert first unit to the second unit in convert:
iex(3)> Exun.Unit.convert("3[m]","1[cm]",%{}) |> Exum.UI.tostr()
"300[cm]"

factorize(e1, e2, pcontext \\ %{})
Factorize units, as text:
factorize("2[N]","[Kg]")
Link to this function
factorize_ast(arg1, arg2, pcontext)
Factorize unit u2 from u1, for example
iex(1)> {u1,d} = Exun.parse "1[km*Kg*A/h^2]", %{}
{u2,d} = Exun.parse "1[N]", %{}
factorized = Exun.Unit.factorize(u1,u2,%{})
