Formula
The PPM Calculator uses the formula:
Concentration = Mass of solute ÷ Mass of solution × 1000000
Worked example
For example, with mass of solute of 0.5 g and mass of solution of 1,000 g, the concentration is 500.00.
| Mass of solute | 0.5 g |
|---|---|
| Mass of solution | 1,000 g |
| Concentration | 500.00 |
|---|

Frequently asked questions
Divide the solute mass by the total solution mass and multiply by one million. 0.5 g in 1000 g is 500 ppm.
Parts per million expresses very small concentrations — how many units of solute per million units of solution.
For dilute water solutions, 1 ppm is approximately 1 mg/L, since a litre of water weighs about 1 kg.
It is common for water quality, air pollution, and trace contaminants where percentages would be tiny fractions.
