Many computer languages (and Excel) use the caret "^" to indicate an exponent. To me, that is the most clearcut when a superscript is not available.

That last sentence suggests an "m" followed by a caret (^) followed by "2". My mail reader automatically reformatted that using superscripts. My point was, carets can be used to indicate superscripting the following digit(s).
