Volt/ohm is not translated in Ampere
1volt/1ohm = 1e0 ampere⁻³ meter⁴ kilogram² second⁻⁶
should be
1volt/1ohm = 1e0 ampere
Thanks Nicola

reporter Thanks, now I understand.
However isn't it a little unusual to have to write 1 volt / (1 ohm) for meaning 1 volt / 1 ohm, like I would write it on paper? I understand that there is a degree of ambiguity in writing 1 volt / 1 ohm and other more complicated calculations. Maybe you already discussed this, sorry that I haven't read all threads about.

No problem. We decided to give implicit multiplication the same precedence as explicit multiplication for simplicity. Otherwise people would wonder why
1/2 x
is not equal to1/2*x
.The units are treated like any other variable and just multiplied with the numeric value. Mathematically this may be debatable, but it greatly simplifies the the parser.
Those two decisions together account for the behaviour you see. While (arguably) not the most intuitive, it is simple to understand.

You need to use parentheses. Your input is interpreted as
(1volt/1) ohm
.
