5000 ppm equals what percent by weight?

Explanation:
Parts per million is a way to express a very small concentration. To convert to percent by weight, divide by 10,000 because 1% equals 10,000 ppm. So 5000 ppm ÷ 10,000 = 0.5%, which is why the value is 0.5% by weight. For reference, 0.05% is 500 ppm, 5% is 50,000 ppm, and 50% is 500,000 ppm, so those options don’t match 5000 ppm.
