Frequently asked questions
- What does ppm mean?
- Parts per million: 1 ppm = 1 mg per litre in dilute aqueous solutions. It can also mean 1 mg per kg (mg/kg) in solid mixtures — the context matters.
- When are ppb values used?
- Parts per billion (ppb = µg/L) are used for trace contaminants in drinking water, air quality, and toxicology where concentrations are extremely low.
