We are basically the last country to not use the metric system in our day to day lives - we measure temperature in Farenheit, distances in feet.yards and miles, and have a ridiculous volume and weight measurement system of cups, ounces, quarts, gallons, etc.
Its an antiquated system that costs the US milions each year by having to convert, tool things in english units (5/8 in wrenches?) etc. Our kids need to learn both systems, and tend to learn neither well.
Why is there no active movement in the US to upgrade our systems?
Why dont we just bite the bullet and change already?
Nice article that may jump start the popular cry: Why Americans still use Fahrenheit long after everyone else switched to Celsius - Vox
