Field notes
The tool derives concentration from the mass and volume printed on a label, then applies that relationship in either direction: mass to volume or volume to mass. It also offers a density path for whole substances, explicitly distinguishing density from active-ingredient concentration. A reference table can show mass at selected volumes, while batch mode accepts up to 250 values and can copy results or download a CSV.
