\nThis is in LaTeX, and the units don't match the surrounding text. I used \\, to put a space between the number and the units.
\nI have $15 \\text{ μm}$ of stuff.
\nThis uses the \\text
command and the Unicode μ character, so the units match the text and the only characters rendered in the LaTeX font are the numbers.
I have $15$ μm of stuff.
\nThe units are completely outside the LaTeX environment. This is easier to write than the \\text
version, but you can't always arrange for the units to be at the end of the LaTeX expression.
When you use English phrases in equations, make sure they're rendered in \\text, or they'll look terrible.
\n\\[ \\frac{\\text{amount of stuff}}{15 \\times(\\text{stuff quotient})} = x \\]
\n(by the way, unicodeit.net is a great tool to help you find the Unicode characters for things like Greek letters - you type in the LaTeX command, and it gives you the corresponding symbols to paste in anywhere)
