PPM Concentration Converter
Convert concentration units between ppm, ppb, ppt, percent, mg/L and µg/L with water-solution assumptions spelled out.
For dilute water solutions 1 mg/L = 1 ppm exactly (density 1 g/mL). For other liquids, mass/volume units scale with the density field. Percent here is w/w: 1% = 10,000 ppm. "ppt" means parts per trillion here (not parts per thousand).
