# metric

If something’s metric, it’s related to a system that uses the meter as a basic measurement. If someone says they'll sell you 3 meters of silk, then you know that the metric system is being used.

The word metric traces back to the French word métriquei, from mèter. The word is most often used to describe a widely used system of measurement based on the meter, called the metric system. Metric can describe the system as well as things related to the metric system. If your science teacher asks you to measure an object using metric units, you’ll be using centimeters and millimeters, rather than inches or feet. In music, metric refers to the rhythmic measures.
