So I started putting together a spreadsheet based on some math I've learned on this forum and other places. I was inspired by the EZ Water Calculator 2.0 and wanted to make a companion for it to complete the brewing mathematics. I guess if you have software, it does all this for you, but I'm not a big fan of paying for something I can do myself. Please take a look and let me know what you think. It's not much, but I'd like to know if any of my formulas are inaccurate because I'd like to start using it.
