Concentration (Solution) Converter
Mass concentration is the mass of a dissolved substance per unit volume of solution. The SI unit is the kilogram per cubic metre. For dilute solutions in water, 1 mg/L is approximately one part per million by mass.
1 Kilogram/Liter = 1,000,000 Part Per Million
How to convert Kilogram/Liter to Part Per Million
One Kilogram/Liter equals 1,000,000 Part Per Million, so multiply any value in kg/L by 1,000,000 to get ppm. To convert back, divide by 1,000,000 — or multiply by 0.000001.
ppm = kg/L × 1,000,000
Example: 25 kg/L × 1,000,000 = 25,000,000 ppm.
