PPM to mg/L Converter
Instantly convert Parts Per Million (PPM) to Milligrams per Liter (mg/L) and other units.
Note: 1 PPM = 1 mg/L for water solutions at standard conditions (1 kg/L density). For gases, conversion depends on molecular weight and temperature.
Easily convert Parts Per Million (PPM) to Milligrams per Liter (mg/L), Micrograms per Cubic Meter (µg/m³), and Grams per Liter (g/L) with our free online tool. Fast, accurate, mobile-friendly—get instant results now.
Introduction

This online tool simplifies those conversions with instant, accurate results—ideal for students, researchers, technicians, and environmental analysts alike. Whether you’re monitoring water quality, conducting lab tests, or working on industrial safety, this converter saves time and reduces errors.
What is PPM (Parts Per Million)?
Parts Per Million (PPM) is a unit of concentration that denotes the number of units of a substance per one million units of total volume or mass. Originating in the scientific and engineering fields, PPM is used to express very dilute concentrations of substances, particularly in air, water, and soil.
Significance and Common Uses:
- Monitoring pollutants in air or water
- Chemical dosing in laboratories
- Quality control in manufacturing
- Agricultural soil nutrient analysis
Conversion Formulas & Explanation
Here are the standard conversion formulas used by the tool:
- PPM to mg/L (Milligrams per Liter):
1 PPM = 1 mg/L (in water at 1 g/mL density)
Example: 50 PPM = 50 mg/L - PPM to µg/m³ (Micrograms per Cubic Meter):
1 PPM ≈ 1000 µg/m³ (depends on substance and temperature)
Example: 2 PPM ≈ 2000 µg/m³ - PPM to g/L (Grams per Liter):
1 PPM = 0.001 g/L
Example: 500 PPM = 0.5 g/L
Note: For gases, the conversion may vary based on molecular weight and temperature.

Frequently Asked Questions (FAQs)
1. What is PPM (Parts Per Million)?
PPM is a unit that describes the amount of a substance in a million parts of the total mixture, often used to measure very small concentrations in water, air, or soil.
2. How do I convert PPM to mg/L?
For water solutions, 1 PPM equals 1 mg/L, because the density of water is approximately 1 g/mL.
3. Does PPM mean the same thing in air and water?
Not exactly. While 1 PPM ≈ 1 mg/L in water, for gases, the conversion to µg/m³ depends on molecular weight and temperature.
4. Can I use this tool for gas conversions?
Yes, but be aware that PPM to µg/m³ for gases depends on the specific gas and conditions. Always check the context or use substance-specific factors.
5. Is this online converter free to use?
Yes! The tool is completely free, mobile-friendly, and designed for fast, accurate conversions.6. Who can benefit from using this converter?
Students, teachers, lab technicians, engineers, environmental scientists, and anyone needing precise chemical or environmental calculations.
