Reference
How concentration - solution conversion works
Solution mass concentration expresses solute mass divided by total solution volume. Values are normalized to Kilogram/liter before conversion to the requested output unit.
Values are converted to kilogram/liter first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Questions
Concentration - Solution FAQ
What is the reference unit for concentration - solution conversions?
ConvertWin uses kilogram/liter (kg/L) as the internal reference for this category, then converts to the selected output unit.
How accurate is this concentration - solution converter?
SI relationships follow the cited reference. Conventional and domain-specific factors use the established ConvertWin factor inventory; verify safety-critical work against the governing standard.
