Concentration calculator

Understand the relationship between mass, volume and concentration. A mathematical tool for solutions, with no dose or administration recommendations.

Enter the final volume; do not assume it equals the amount of solvent added. A decimal point or comma is accepted.

THE FORMULA, EXPLAINED

Concentration =
mass ÷ volume

1 mg = 1,000 µg

Amount in a sample = concentration × sample volume. Results are rounded to at most 8 significant digits.

Inputs are calculated in your browser, without being saved or transmitted by this calculator. The result does not verify purity, sterility, stability or suitability for human use. mg, mL and biological units are different quantities; this calculator does not turn its result into an injection recommendation.
