Something that often comes up is needing to make adjustments and sometimes it’s just easier to pull out a calculator and do the math yourself. I have a clipboard that my brewday sheet goes on, and I’ll be sticking this onto it so whenever I need to make an adjustment to kettle volumes or figure out a step addition I have all the math I need.

A lot of this is taken from the How to Brew site, but I just made them a bit more readable compared to what is currently available up there. Keep in mind my adjustments are all in metric since that’s what system I do all my brewing in.
