Answer:
metric
Explanation:
Unlike the United States, most countries across the globe rely on the metric system to measure units, creating problems for both buyers and sellers in the international marketplace.
The United States uses the imperial system, also known as the U.S. Customary System.
For example, to measure length, the imperial system uses units such as inches, feet, yards, and miles. On the other hand, the metric system uses units such as millimeters, centimeters, meters, kilometers, etc.
