ppm = mass_solute_mg / mass_solution_kgConcentration
ppb = (mass_solute_mg / mass_solution_kg) * 1000Variables
| Variable | Description | Default |
|---|---|---|
mass_solute_mg | Mass of Solute(mg) | 5 |
mass_solution_kg | Mass of Solution(kg) | 1 |
How It Works
How to Calculate PPM
Formula
ppm = mass of solute (mg) / mass of solution (kg)
Equivalent to mg/L for dilute aqueous solutions. 1 ppm = 1 part per 1,000,000 parts.
Worked Example
5 mg of fluoride in 1 kg of water.
mass_solute_mg = 5mass_solution_kg = 1
- 01ppm = 5 mg / 1 kg
- 02ppm = 5 ppm
