To convert to US gallons:

V = (pi * r2 * h) / 231

Where pi = 3.1416, r is the radius of your kettle (diameter divided by 2), and h is the height of your liquid in inches. This will give you a cubic inches figure which is why you divide the answer by 231 to convert to US gallons.

Great idea. I'm going to add this to my brew workbook. Brewday will be even better/easier.

Hey thanks Wrenchman. I didn't get a post notification for some reason.

Can't look at this from my phone but does it take into account the 2 bump outs on the kegs?

I have site gauges on my gear but I made the same thing for my buckets/carboys. This let's me know what my final yield was using a tape measure. Ahhh, math. So useful.

I was just about to post a question on this. Glad I found the thread! Measuring the volume and chugging through the cylinder volume calc seem like the way to do things for me from now on. It occurred to me on my last brew as im trying to do full volume boils and have been off a bit. Will use this to accurately get volume not just in my kettle but also in my buckets!
