-
Choose the desired target concentration unit.
-
Click the convert button to receive the equivalent value instantly.
Key Features
-
Converts numerous concentration units such as Percent by Mass, Parts per Million, Grams per Liter, and more.
-
Utilizes direct unit-to-unit conversion factors without converting through a single base unit to maintain accuracy.
-
Supports exact mass–volume conversion factors with optional rounding to scientific or regulatory standards.
-
Includes units used in laboratory, environmental, agricultural, and industrial contexts.
Examples
-
Converting 1 g/L to mg/L gives 1000 mg/L.
-
Converting 10 ppm to grams per cubic meter results in 0.01 g/m³.
Common Use Cases
-
Laboratory chemical solution concentration conversions.
-
Pharmaceutical formulation and dosage calculations.
-
Environmental monitoring of trace substances in water and air.
-
Water treatment and chemical dosing operations.
-
Agricultural chemical concentration adjustments.
Tips & Best Practices
-
Ensure correct interpretation of units that may represent mass or volume depending on context.
-
Verify that source data accurately reflects the unit type before conversion.
-
Use appropriate rounding options to meet scientific or regulatory requirements.
-
Confirm unit compatibility especially when working across metric and customary systems.
Limitations
-
Some units like Percent Mass/Volume (% w/v) and Parts per Million (ppm) may refer to either mass or volume, requiring careful interpretation for accurate conversion.

Key Terminology
-
Percent by Mass (% w/w)
-
The mass of solute divided by the mass of the solution, multiplied by 100.
-
Parts per Million (ppm)
-
The mass or volume of solute per one million parts of the solution.
-
Milligrams per Liter (mg/L)
-
A concentration unit indicating milligrams of solute in one liter of solution, commonly used in environmental and water chemistry.
