Concentration calculator
MG to PPM Calculator
Convert milligrams to parts per million using a stated solution volume or mixture mass. This calculator avoids the common mistake of treating a standalone mg value as a ppm value.
mg
What is a milligram?
A milligram is a metric unit of mass equal to one-thousandth of a gram.
ppm
What is parts per million?
PPM is a concentration ratio meaning one part of a substance per one million parts of the mixture on a stated basis.
—For dilute water, mg/L ≈ ppm.
MG to PPM Formula
ppm ≈ mg ÷ liters (dilute aqueous solution)

PPM to MG Formula
The same calculator also works in reverse when the final solution volume is known.
mg ≈ ppm × liters (dilute aqueous solution)
For non-aqueous liquids or solid mixtures, use the correct mass basis and density instead of assuming mg/L equals ppm.
1–1000 MG to PPM Reference Table
Reference basis: each mg amount dissolved to a final volume of 1 liter of dilute water.
Complete 1–1000 Conversion Table
Reference basis: 1 L dilute aqueous solution.

Frequently Asked Questions
What is the difference between PPM and mg/L?
For dilute water-based solutions, 1 mg/L is approximately 1 ppm. For other media, density and the concentration basis matter.
How do I convert mg to ppm?
For an aqueous solution, divide the solute mass in mg by the solution volume in liters to get mg/L, which is approximately ppm when water density is near 1 kg/L.
Is 1 mg/L exactly 1 ppm?
It is an approximation for dilute aqueous solutions. PPM is fundamentally a parts-per-million ratio.
Can I calculate ppm for solids?
Yes. A common mass basis is mg of substance per kg of total mixture.
What does 1 ppm mean?
One part of a substance per one million parts of the mixture, on a stated basis.
Methodology and Sources
The calculator requires the denominator or molecular information that the scientific conversion actually needs. Assumptions are stated next to the result rather than hidden.
