ヘクタール
1. hectareFrom French
2. HectareThe hectare is a metric unit of area defined as 10,000 square metres (100 m by 100 m), and primarily used in the measurement of land. In 1795, when the metric system was introduced, the 'are' was defined as being 100 square metres and the hectare was thus 100 'ares' or 1/100 km. A hectare of land is about 2.47 acres. When the metric system was further rationalised in 1960, resulting in the International System of Units (SI), the are was not included as a recognised unit.
