The hectare is not officially included in the International System of Units, or SI, metric system. A hectare, in metric terms, is equal to 10,000 square meters, or 104 m2. The status of the hectare is that of a "non-SI unit" that is accepted for use with SI units, and it is also considered a unit whose use is "expected to continue indefinitely," as noted in Section 4.1 of the SI literature. Trafalgar Square in London, England represents an area of about 1 hectare.
