How many pixels, inches or centi meters is a linewidth in a two columned article?

Question

I'm writing an article. The article consists of two columns and is created using:

\documentclass[10pt, aps, prb, twocolumn]{revtex4-1}

How long is a 1.\linewidth in pixels, inches or centi meters?

\linewidth doesn't have a fixed value (see http://tex.stackexchange.com/questions/16942/difference-between-textwidth-linewidth-and-hsize). You probably want to know the value of \columnwidth: see http://tex.stackexchange.com/questions/558/is-there-a-show-for-lengths — egreg, Jun 09 '14 at 21:33

You can find out by asking LaTeX itself.

Open a console/terminal window, and type latex.

LaTeX will respond with some version information text and then a prompt **. You can then issue commands, as

**\documentclass[10pt, aps, prb, twocolumn]{revtex4-1}
*\begin{document}
*\showthe\linewidth

LaTeX will then return the value of \linewidth, which on my system is 246.0 pt.
