This question already has an answer here:

What symbol represents "has the dimensions of", as in "x has the dimensions of d"? Does such a symbol exist?

AFAIK there isn't a symbol for that exact purpose. I'd just write "x has the same dimensions as d". –  Benjamin Hodgson Oct 11 '12 at 21:33

Some people use square brackets to denote dimension. I'm not 100% sure if they are used in this case.

I would use these if you are desperate but be explicit and don't assume the reader understands.

R = $[J] [K^{-1}] [mol^{-1}]$

edit: on the other hand


Buckingham Pi Theorem uses dimensional analysis, wikipedia uses lower case to denote the dimensions. I think that is confusing at first sight.
