It is commonly used in many countries—in particular, in French-, Portuguese-, Polish- Dutch- and German-speaking countries—to measure real estate; elsewhere, the square metre is usually used. The are is sometimes used in combination with the centiare, e.g. "10 ares 12 centiares" = 1012 m². Larger land areas are generally measured in hectares.
