The two main differences are simplicity and universality.
The metric system is much simpler since any measure of a particular characteristic is related to other measures of the same characteristic by powers of 10. With the US (or Imperial system, there are a huge number of conversion factors. For example:
- 2 pints in a quart
- 3 feet in a yard
- 4 quarts in a gallon
- 6 feet in a fathom
- 8 furlongs in a mile
- 9 square feet in a square yard
- 12 inches in a foot
- 14 pounds in a stone
- 16 ounces in a pound
Also, units for different characteristics are also linked by simple factors. For example, a hectare (area) = 10,000 square metres, or 1000 litre = 1 cubic metre.
In terms of universality, all countries in the world with the exception of the recalcitrant three: US, Burma and Liberia, plus some island states, have adopted the metric system.

Is teaspoon customary or metric?
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!

well the USA is the only country in the world to use the customary system while the rest of the world uses the metric system

We, who do not live in the US don't!
