实际应用场景

中国的房地产市场使用平方米作为标准面积单位。北京一套100平米的公寓、上海浦东200平米的大平层、深圳50平米的小户型, 这些都是常见的用法。但海外房产网站Zillow或Realtor.com上的房源用平方英尺显示，需要换算才能与中国买家习惯的面积概念对应。一亩（约666.7平方米）是农村土地丈量的常用单位，农民说「我有五亩地」非常普遍。但国际农业统计用公顷，1公顷=15亩。室内装修时，地板和瓷砖按平方米购买，从美国进口的地毯尺寸却用平方英尺标注。在地理上，中国960万平方公里陆地面积在向外国人介绍时，有时需要转换为平方英里。香港的房地产广告用平方呎（平方英尺），与内地平方米之间的换算让跨境购房者头疼。
