ppm = mg ÷ kg
What Is ppm?
ppm (parts per million) is used to express very low concentrations. It indicates the number of solute units per one million units of solution.
How is it calculated?
How Is It Calculated?
ppm = (solute ÷ solution) × 10⁶
- Enter the amount of solute and solution.
In dilute water, 1 ppm ≈ 1 mg/L.
Frequently Asked Questions
Where is ppm used?
It is used for very low concentrations such as water quality, air pollution and trace element measurements.
