Percent mass per volume to Parts per million in dilute water (≈ mg/L)
1 %w/v ≈ 10,000 ppm (water ≈ mg/L). Edit either value to convert instantly.
Conversion formula
ppm (water ≈ mg/L) = %w/v × (10) × (1,000)1 %w/v ≈ 10,000 ppm (water ≈ mg/L)
percent mass per volume (%w/v)
percent mass per volume is a unit of solution mass concentration: 1 %w/v = 10 kg/m³. Here 1 %w/v means 1 g of solute per 100 mL of final solution; it is not a mass fraction.

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 percent mass per volume?
1 %w/v ≈ 10,000 ppm (water ≈ mg/L). ppm (water ≈ mg/L) = %w/v × (10) × (1,000)
How do I convert %w/v to ppm (water ≈ mg/L)?
ppm (water ≈ mg/L) = %w/v × (10) × (1,000)
Is 1 percent mass per volume bigger than 1 part per million in dilute water (≈ mg/L)?
1 %w/v ≈ 10,000 ppm (water ≈ mg/L).
