在生产中我们通常用米尺(或米绳)丈量土地。在生产管理中习惯用“亩”作为士地的面积单位,如亩施肥量,亩用药量,亩灌水量等。这样就需进行平方米与亩的换算。若用一亩=666.7“平方米”的关系换算比较麻烦。现介绍一种简单、准确实用的计算方法。可概括为四句话:量地用米绳,长宽来相乘。添零 In production we usually use the meter (or meter rope) to measure the land. In production management, it is customary to use “mu” as an area unit of land, such as the amount of fertilizer per mu, the amount of mu used, and the amount of irrigation for mu. This requires the conversion of square meters and acres. If a mu = 666.7 “square meters” the relationship between the conversion is too much trouble. Now introduce a simple, accurate and practical method of calculation. Can be summarized as four sentences: the amount of rice rope, length and width to multiply. Tim zero
