Saponification Value Calculator
Calculate the saponification number of fats and oils
Formula: Sap Value = [ (Vblank − Vsample) × N × 56.1 ] / W
Where V is titration volume (mL), N is normality of KOH, and W is fat/oil mass (g).
Where V is titration volume (mL), N is normality of KOH, and W is fat/oil mass (g).

Calculation Results
⚠️ Saponification value indicates the average molecular weight (or chain length) of fatty acids in an oil sample. Lower saponification values correspond to higher molecular weight fatty acids (longer carbon chains). Always ensure complete saponification during reflux heating [cite: "Calculators Tools - Correct"].
