Which system is used by most of the world, aside from US customary units?

• A. Imperial system
• B. Metric system
• C. US Customary Units
• D. Natural units

Answer: (B)

The metric system is used by most of the world because it is decimal-based and standardized, making it easy to convert between units. It’s the system that defines base units like the meter, gram, and liter and uses prefixes such as kilo-, centi-, and milli to scale by powers of ten. This coherence supports science, industry, and international communication, which is why countries worldwide adopt it alongside US customary units. The Imperial system is mostly limited to a few regions and historical use, US customary units are primarily used in the United States, and natural units are specialized for physics rather than general measurements.
