I recently got an interest in anodizing at home. One of the key
ingredients called for by most home-brew anodizing methods is battery
(sulfuric) acid. I went to my local auto parts store and purchased 6
quarts of battery acid with a specific gravity of 1.265. How can I
convert that number to a percent solution?

Thanks

I had the same query a while back.
