I greatly prefer the elegant, simple, easy to learn and teach International System of Units (meter, kilogram, et cetera) to the klutzy, complicated, hard to learn and teach United States Common System of units (foot, slug, et cetera). – Laran Stardrake
As our tiny contribution to metric enlightenment, we are writing Metric Backpack, tools & toys to help learners learn, and teachers teach, the International System of units, commonly called the metric system in the USA. We hope you find this information interesting, useful, et cetera. We will appreciate it greatly if you inform us of any mistakes.
