在农林生产中,计算地亩是经常碰到的一个问题。为了提高计算效率,减少繁琐的乘除方法,以方便群众,有利于生产,我们在工作实践中,探索编制了地亩面积查算表。一般计算面积的方法是:长乘宽得平方米除以666·67,即为所需要的实际亩数。但近年来广大群众在实践中总结了经验,作了如下一些改进:1、群众有16大步(1大步为5市尺)长乘15大步宽得240平方大步为1亩的方法;2、把长乘宽的平方米再乘以0·0015得亩数,或平方米加一半,小数前移3得亩数;
In the production of agriculture and forestry, the calculation of acres is a frequently encountered problem. In order to improve the computational efficiency and reduce the cumbersome multiplication and division methods in order to facilitate the masses and facilitate the production, we explored and compiled the acreage checklist for acreages in our work practice. The general method of calculating the area is: Long Square meters divided by 666.67 square meters, which is the actual number of acres needed. However, the masses in recent years summed up the experience in practice, made the following improvements: 1, the masses have 16 stride (1 stride to 5 feet) long by 15 stride width of 240 square stride to 1 acre method ; 2, multiply the long and wide square by 0.0015 multiplied by the number of acres, or half of the square, the decimal forward 3 to obtain the number of acres;
