1.亩换算成平方米口诀:原数减三分之一,小数后移三。例1:求:94.5亩=xm2解:x=94.5-94.5 ÷ 3=63小数后移三位得:x=63000(m2) 2.平方米换算成亩,口诀:原数加一半,小数前移三。例2:求:1520m2=x亩解:X=1520+ 1520÷2=2280小数前移三位得:x=2.28(亩)亩与平方米换算口诀@陈佩富
1. Acre converted into square meters Formula: the original number by one-third, after the decimal three. Example 1: Find: 94.5 acres = xm2 Solution: x = 94.5-94.5 ÷ 3 = 63 Decimal shift three: x = 63000 (m2) 2. Square meters converted into mu, formula: the original plus half, before the decimal Move three. Example 2: Seeking: 1520m2 = x mu solution: X = 1520 + 1520 ÷ 2 = 2280 decimal forward three were: x = 2.28 (mu) mu and square conversion formula @ Chen Peifu
