PPM to mg/L Converter

Convert ppm to mg/L (for water).

mg/L (mg/L) 200

Formula: For water, ppm = mg/L

Step-by-step with your numbers:

1. Values used:

2. PPM = 200 ppm

4. mg/L = 200mg/L

Did we solve your problem today?

In water, 1 ppm ≈ 1 mg/L (since 1 L of water is ~1 kg).

The math behind it

mg/L = ppm (for dilute aqueous solutions, water density ≈ 1).

200 ppm = 200 mg/L.

Not water?

For liquids of different density, mg/L = ppm × density.
