I had to learn the arcane world of pipe fitting sizes working with pneumatics for a scuba equipment project. It is extremely confusing. Unfortunately, it can have fatal consequences. In a recent story, a scuba store employee used the wrong size fitting on a 3,000 psi scuba tank which shot out and killed them.

Seeing that American can't even adopt the metric system, I have little hope for a clear international standard for pipe fittings.

All Americans completely understand the metric system. We can convert anything to anything in our heads. By the way, we all speak a dozen foreign languages fluently, just choose not to. It is because we are so humble that you do not know this.

I was with you till you asserted we only speak a dozen languages.
