Milligrams per deciliter to Parts per million in dilute water (≈ mg/L)
1 mg/dL ≈ 10 ppm (water ≈ mg/L). Edit either value to convert instantly.
Conversion formula
ppm (water ≈ mg/L) = mg/dL × (0.01) × (1,000)1 mg/dL ≈ 10 ppm (water ≈ mg/L)
milligram per deciliter (mg/dL)
milligram per deciliter is a unit of solution mass concentration: 1 mg/dL = 0.01 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.

Frequently asked questions
How many parts per million in dilute water (≈ mg/L) are in 1 milligram per deciliter?
1 mg/dL ≈ 10 ppm (water ≈ mg/L). ppm (water ≈ mg/L) = mg/dL × (0.01) × (1,000)
How do I convert mg/dL to ppm (water ≈ mg/L)?
ppm (water ≈ mg/L) = mg/dL × (0.01) × (1,000)
Is 1 milligram per deciliter bigger than 1 part per million in dilute water (≈ mg/L)?
1 mg/dL ≈ 10 ppm (water ≈ mg/L).
