How to Convert Mass Concentration Units
Mass concentration is the mass of a dissolved substance per unit volume of solution. The SI unit is kilogram per cubic metre (kg/m³); water analysis usually reports mg/L, which equals ppm by mass for dilute aqueous solutions.
Every unit on this page is stored as a fixed factor relative to one reference unit, the kilogram per cubic metre (kg/m³). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in kg/m³.
- Divide that result by the factor of the target unit.

Frequently Asked Questions
What is the SI unit of mass concentration?
The SI unit of mass concentration is the kilogram per cubic metre (kg/m³). Mass concentration is the mass of a dissolved substance per unit volume of solution.
How do I convert mg/L to g/L?
To convert milligram per litre (mg/L) to gram per litre (g/L), multiply the value in mg/L by 0.001. For example, 1 mg/L = 0.001 g/L.
How do I convert ppm to mg/L?
To convert part per million (in water) (ppm) to milligram per litre (mg/L), multiply the value in ppm by 1. For example, 1 ppm = 1 mg/L.
How do I convert gr/gal to mg/L?
To convert grain per gallon (us) (gr/gal) to milligram per litre (mg/L), multiply the value in gr/gal by 17.1181. For example, 1 gr/gal = 17.1181 mg/L.
