What Is PPM?

Parts per million (ppm) is a unit of measurement used to express very small concentrations. It describes the number of parts of a substance per one million parts of the total mixture. PPM is commonly used in water quality, air quality, food science, and manufacturing.

How to Convert Percent to PPM

Percent to PPM Formula

ppm = % ร— 10,000

The conversion factor is 10,000 because 1% = 1/100, and 1 ppm = 1/1,000,000. The ratio is 1,000,000/100 = 10,000.

Quick reference: 1% = 10,000 ppm. 0.1% = 1,000 ppm. 0.01% = 100 ppm. 0.001% = 10 ppm.
