Percent = PPM ÷ 10,000. For example, 500 ppm = 0.05%.

How do I convert PPM to PPB?

PPB = PPM × 1,000. For example, 1 ppm = 1,000 ppb.

PPM is used for dilute concentrations: water quality, air pollution, chemistry, food safety.

Convert between parts per million (PPM), percent (%), and parts per billion (PPB).
