Customary Units
The united states used the customary system when the british brought here before the revoluitionary war. only the us, UK, myanmar, and Liberia still use the systems of measurement.
The teaspoon is a traditional customary measurement that has been standardized in manufacturing practice and in food service / food labeling to equal an exact metric equivalent. In the United States one teaspoon as a unit of customary culinary measure is 1⁄3 tablespoon, that is, 4.92892159375 mL; it is exactly 1⁄3 US fluid drams, 1⁄6 US fl oz, 1⁄48 US cup, and 1⁄768 US liquid gallon and approximately 1⁄3 cubic inch. For nutritional labeling on food packages and in food service in the US, the teaspoon is defined as precisely 5 mL, the tablespoon as 15 mL. Almost ALL less expensive teaspoon measures sold in the US since the late 1950's have held an exact 5mL (overseas manufacturing is metric and they simply rounded up) - so you have been likely using the metric system for many years thinking you were using a customary measure without knowing it!

Of course, and considered it during WWI. Metric measurement is legal for trade in the US, but it's time to get rid of archaic measurement and catch up with the world.
Sell/buy more drugs. That's how I learned metric.
The SI unit is a Newton. The old US unit is the pound-force or the poundal.
