i'm an american.
Sorry, I guess I should have said universal except for the United States.
Why are so many americans opposed to the metric system? The only primary numbering system taught in schools is base-10, so it's not like it's some weird foreign concept....
I mean no offense, I've just never discussed it before. And USA is one of only a handful of countries not using the metric system.
I'm certainly not opposed to the metric system. But I also know that there is a stack of patchwork government regulations which mandate Imperial measurements (sometimes, along with metric).
I do of course realize that there are a ton of legacy rules and regulations with regards to SAE in America, and that it would not be an overnight change. But it would likely make for a lot less work and confusion for some people who must deal with both systems for their job or whatever.
