How the result is worked out
Mass and volume use exact SI factors. Concentration conversions assume a dilute aqueous solution with a density of 1 g/mL, so 1 ppm equals 1 mg/L. Temperatures convert between °C, °F and K.
Good to know
- ppm by mass and mg/L are only equal for dilute water-based solutions.
- 1 US gallon is 3.785 L, an imperial gallon is 4.546 L.
- Freight weights are usually quoted in kg or MT (1 MT = 1,000 kg).
