As far as I know, the proper way to typeset values and dimensions is to use units package. When you want to write 1 mm, you use: \unit[1]{mm}. In Lyx, if I select that expression and press Ctrl+M to convert it to a formula, I works perfectly. But if I start math mode first by pressing Ctrl+M and type \unit[... it does not seem to work. Anyone has an idea how to do that?
