" Precision" is often used for things related to measurement, although " accuracy" can also describe numerical measurement as well.

“精度” 通常用于与测量相关的事物，尽管“准确度” 也可以描述数值测量。

Since, therefore, real income, in terms of product, may be incapable of precise numerical measurement, it is often convenient to regard income in terms of wage-units (Yw) as an adequate working index of changes in real income.

因此，由于以产品表示的实际收入可能无法进行精确的数值测量，因此将以工资单位 (Yw) 表示的收入视为实际收入变化的适当工作指标通常很方便。
