Metric (SI)- The universal measuring unit!
We are living in a metric world where just about every country, except the USA, uses the metric system, and other countries are now telling us that they don't want to buy some of the products manufactured by U.S. companies if they aren't made to metric sizes (and if they aren't labeled in metric units). Many European Union (EU) countries, which have been good customers of U.S. companies, don't allow products into their countries unless they are made to metric system standards. We must operate in the world marketplace, and we can't stay competitive if we don't provide metric goods. With 99\% of the rest of the world using metric, there is no chance we can persuade them to use our inches and pounds.
