Kilograms per cubic meter to Parts per million in dilute water (≈ mg/L)
1 kg/m³ ≈ 1,000 ppm (water ≈ mg/L). Edit either value to convert instantly.
Conversion formula
ppm (water ≈ mg/L) = kg/m³ × (1) × (1,000)1 kg/m³ ≈ 1,000 ppm (water ≈ mg/L)
kilogram per cubic meter (kg/m³)
kilogram per cubic meter is a unit of solution mass concentration: 1 kg/m³ = 1 g/L.

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.
