Alligation Calculator
Calculate mixing ratios for solutions of different concentrations
Alligation Alternate Method: Parts of Higher = (Desired - Lower). Parts of Lower = (Higher - Desired). The desired target concentration must be strictly between the higher and lower values.
Concentrations (%)
Final Volume / Mass (Optional)
Calculation Results
⚠️ In pharmaceutical compounding and chemistry, mixing two different liquid solutions may result in slight volume contraction or expansion. Using mass (grams/kg) provides perfect accuracy. If using volumes (mL/L), verify the final volume in a graduated cylinder.
