Who's good enough at math to figure this out? I have a cigar that I need to figure out the ring gauge for. The catalog doesn't give it. It gives the diameter as 20 mm, which is approx 0.78 of an inch. Ring gauge is measured in 64ths of an inch. So a 64 ring gauge is a 1 inch diameter cigar and a 32 ring gauge is a 1/2 inch diameter. So what is the ring gauge of a .78 inch cigar? :|
