MG Per Liter to Part/million (PPM) Calculator
Milligram per Liter to PPM Calculator
Enter your concentration value in mg/L field for example 1.5 mg/L, the milligram per liter to ppm calculator will convert concentration in 1.50 ppm.
How to Convert mg/L to PPM?
- Ensure you’re working with water or a dilute aqueous solution.
- Use formula ppm = mg/L to convert mg/L to ppm.
A water sample containing 2.7 mg/L of fluoride would have a concentration of 2.7 ppm, making it straightforward for water quality monitoring and reporting.

Mg/L to PPM Conversion Formula
The formula is remarkably simple:
1 mg/L = 1 ppmppm = (mg of solute / L of solution) × (density of water / density of solution)Measuring nitrate levels in groundwater at 45.3 mg/L. Given our direct relationship in water-based solutions, this converts directly to 45.3 ppm, a level that would warrant attention from environmental authorities.
Analyzing dissolved iron content of 0.3 mg/L in drinking water converts to 0.3 ppm, which falls within many regulatory limits for acceptable iron content in drinking water.
Measuring phosphate levels of 2.5 mg/L in a lake sample would equal 2.5 ppm, potentially indicating excessive nutrient levels that could lead to algal blooms.
What is mg/L and PPM?
Milligrams per liter (mg/L) represents the mass of a substance dissolved in a specific volume of solution. It’s particularly useful in water quality analysis and environmental monitoring because it provides a precise measurement of concentration in liquid solutions.
Parts per million (ppm) expresses the ratio of one substance to another in millionths. In water analysis, it represents how many parts of a substance exist per million parts of the total solution. This unit is widely used in environmental science, chemistry, and industrial applications.
