This converter supports 5 units in total, including mol/L, mmol/L, g/L, mg/L, and covers metric, imperial and Chinese traditional systems.
Used in lab solution preparation, water quality testing (e.g., mg/L), and agricultural pesticide dilution.
All values follow internationally accepted definitions and are rounded to the decimals you choose. The calculation runs entirely in your browser, so nothing is uploaded or stored on a server.
History & Background
The precise concept of concentration evolved with analytical chemistry, from early Baume degrees to the modern molarity system.
Conversion Details
Concentration measures solute content. Common units include mol/L (M), g/L, and ppm.
Conversion between mass and molarity requires molar mass; this tool assumes a density of 1kg/L.
