PPM Calculator

PPM Calculator

Select a calculator type below. Each section calculates ppm using its standard definition.

Mass by Mass PPM Calculator

ppm (w/w) = (mass of solute ÷ mass of solution) × 1,000,000

Use any mass unit, but keep it consistent (e.g., g and g).
Total mass of solution (solute + solvent).
Result (ppm)

Mass by Volume PPM Calculator

ppm (w/v) ≈ (mass of solute ÷ volume of solution) × 1,000,000

Commonly mg, g, etc. (keep consistent with your volume basis).
Commonly L (liter). For mg/L, ppm ≈ mg/L (in water-like solutions).
Result (ppm)

Volume by Volume PPM Calculator

ppm (v/v) = (volume of solute ÷ volume of solution) × 1,000,000

Use any volume unit, but keep it consistent (e.g., mL and mL).
Total volume of solution (solute + solvent).
Result (ppm)

Mole by Mole PPM Calculator

ppm (mol/mol) = (moles of solute ÷ total moles of solution) × 1,000,000

Enter moles of solute.
Total moles = solute + solvent (or sum of all components).
Result (ppm)
