Conversion formula

ppm (water ≈ mg/L) = g/L × (1) × (1,000)

1 g/L ≈ 1,000 ppm (water ≈ mg/L)

gram per liter (g/L)

gram per liter is a unit of solution mass concentration: 1 g/L = 1 kg/m³.

part per million in dilute water (≈ mg/L) (ppm (water ≈ mg/L))

part per million in dilute water (≈ mg/L) is a unit of solution mass concentration: 1 ppm (water ≈ mg/L) ≈ 0.001 kg/m³. This is only an approximation for dilute water with density about 1 kg/L: 1 ppm ≈ 1 mg/L. For other liquids or concentrations, density is required.
