Parts per million in dilute water (≈ mg/L) to Milligrams per deciliter
1 ppm (water ≈ mg/L) ≈ 0.1 mg/dL. Edit either value to convert instantly.
Conversion formula
mg/dL = ppm (water ≈ mg/L) × (0.001) × (100)1 ppm (water ≈ mg/L) ≈ 0.1 mg/dL
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.

milligram per deciliter (mg/dL)
milligram per deciliter is a unit of solution mass concentration: 1 mg/dL = 0.01 kg/m³.

Frequently asked questions
How many milligrams per deciliter are in 1 part per million in dilute water (≈ mg/L)?
1 ppm (water ≈ mg/L) ≈ 0.1 mg/dL. mg/dL = ppm (water ≈ mg/L) × (0.001) × (100)
How do I convert ppm (water ≈ mg/L) to mg/dL?
mg/dL = ppm (water ≈ mg/L) × (0.001) × (100)
Is 1 part per million in dilute water (≈ mg/L) bigger than 1 milligram per deciliter?
1 ppm (water ≈ mg/L) ≈ 0.1 mg/dL.
