What is Are?

The are is a unit of area equal to 100 square meters, or a square 10 meters on each side. It was introduced as part of the metric system during the French Revolution. While less commonly used today than the hectare (which equals 100 ares), the are still appears in land registration documents and real estate descriptions in some countries. In Japan and parts of Europe, small plots of land may be described in ares. The prefix "hect-" in hectare literally means one hundred ares.
