Saponification Value Calculator
Result
Saponification Value Calculator Calculate the saponification value (SAP value) of an oil — the amount of KOH needed to saponify one gram of oil — for soap making. — free online calculator.
Formula
- Saponification Value Calculator calculates its result from Lye Factor, Oil G, Sap Value, Superfat. It uses the formula Lye (g) = Oil (g) × SAP value × lye factor × (1 − superfat%). Change any input to recalculate the result instantly.
- The main inputs are Lye Factor, Oil G, Sap Value, Superfat. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Saponification Value
- Lye Factor: 2
- Oil G: 3
- Sap Value: 4
- Superfat: 5
Using Lye Factor = 2, Oil G = 3, Sap Value = 4, Superfat = 5, the calculated result is 22.8.
