Outside the United States, most of the world uses the metric system. Which of the following measurements is NOT part of the metric system?

Ounces are NOT part of the metric system. The equivalent to 10 ounces in metric units would be .28 kilograms, meaning that one kilogram equals about 35 ounces. Amperes and Kelvin are also part of the metric system; so are the second and the mole.
