About mass concentration units
Mass concentration is the mass of solute per volume of solution. Clinical labs in the US report many analytes in mg/dL, while most other countries use mmol/L (see molarity). “ppm” in water quality conventionally means mg/L, which is only exact for dilute water solutions with density 1 kg/L.

Frequently asked questions
What is the SI unit of mass concentration?
This converter uses the gram per liter (g/L) as its reference unit; every other unit is defined relative to it.
How many mass concentration units can I convert?
13 units are supported here, across Metric, SI, Other, US customary systems. Every pair can be converted in both directions.
