✔ 最佳答案

The abbreviation PPM; stands for parts per million. It is a common unit of
concentration of gases or vapour in air. For example, 1 ppm of a gas means
that 1 unit of the gas is present for every 1 million units of air. One ppm is the same as 1 minute in 2 years or 1 cent in $10,000.

In other words 1% = 10,000ppm = 10克/升 = 1克/100毫升 = 10克/公斤 = 1.33盎司以重量/gal水 = 8.34gal水
