统计学中的1%相当于 10000ppm A. 正确 B. 错误

To determine if 1% equals 10,000 ppm, we need to convert both units to a common basis. Percent (%) means "per hundred," so 1% = 1/100 = 0.01. Parts per million (ppm) means "per million," so 1 ppm = 1/1,000,000 = 0.000001.

To convert percent to ppm, multiply by 1,000,000/100 = 10,000. Thus, 1% = 1 × 10,000 ppm = 10,000 ppm. This conversion is widely used in fields like chemistry, environmental science, and quality control to express concentrations of substances.
