This question already has an answer here:

How do i use superscript without using math mode?

I want to write 2 m^{2} (2 squaremeters).

When i use the command m^{2} I get the following error: "Command \ae invalid in mode"

I'm writing my thesis in danish, and have a lot of danish references. Writing the danish letter Æ is only possible using the \ae command in citations.

    tex.stackexchange.com/questions/47324/… perhaps? But you have shown us nothing about your bibliography related content. There might be other/better(?) solutions than \textsuperscript – user31729 Jun 2 '15 at 9:11

    You should use siunitx to get the proper spacing, 2 m^2 (in text mode) will not have the proper spacing between the value and the unit. – daleif Jun 2 '15 at 9:21

Using the command \textsuperscript{ ... } solved the problem.
