Frequently Asked Questions

What does PPM mean?
PPM stands for parts per million. It represents one unit of solute per million units of solution. For aqueous solutions, 1 ppm ≈ 1 mg/L. It is commonly used for trace concentrations in water quality, pollution, and food science.
How do I convert PPM to percentage?
Divide PPM by 10,000 to get percentage. For example, 5000 ppm = 0.5%. Conversely, multiply percentage by 10,000 to get PPM.
