metric systems

Base-ten measurement frameworks

Metric systems are decimal-based systems of measurement in which units scale by powers of ten.

The modern standard is the International System of Units (SI), built on base units like the meter, gram, and liter.

Most of the world uses metric for everyday purposes; the United States remains a notable holdout, though metric appears in science, medicine, and international trade.
