Considering buying a Brix refractometer, just wondering: Is Brix the exact same thing as Plato? I've read that both Brix and Plato readings equal the percentage of sugar in solution by weight. Is there something I am missing?

For instance, since there is other stuff in beer wort than just water and sugar, do you need to correct the Brix readings to get the correct Plato reading?

Thanks for the link! In that one article he talks about a correction factor that you need to use since wort contains stuff other than sugar and water.

And through a US department of agriculture sucrose conversion chart I got from the prodigal, I have gotten confirmation that Brix and Plato are in fact identical. To the last decimal, even. So long as there's only sugar and water, that is
