# Ohm symbol in latex

I have gone through symbol charts of latex and could not find how to put a ohm symbol. Like \theta, \omega, is there some command for ohms symbol?

You can use \usepackage{siunitx}. After that just input as \si{\ohm}. If you want to use a specific value it is better to mark it up like \SI{1}{\ohm}.

Since the ohm symbol is just the non-italic greek omega letter, you can as well use the command \textOmega from the textgreek package, which is in the large symbols table.

Just use \Omega since ohms symbol is uppercase Greek letter omega.

• @JouleV While I do agree that using the math mode symbol $\Omega$ isn't the ideal way to get an Ohm symbol, please note that $\Omega$ is upright. I find the downvote (if it's from you, otherwise sorry) a wee bit exaggerated. – campa Feb 20 at 9:41

• This is a reasonable answer. I don't understand the downvote. +1 – Henri Menke Feb 20 at 10:04
