Soap Mold Volume & Weight Calculator





Notes

  • Specific Gravity Value: The default of 1.08 is an average. Users should adjust this based on their specific recipe, as it varies with ingredients (e.g., heavy oils like coconut or lighter ones like olive oil). If users don’t know their soap’s specific gravity, they can estimate it or measure it by weighing a known volume of their batter.
  • Units: The calculator assumes dimensions in centimeters and specific gravity in g/cm³, yielding weight in grams. If you prefer other units (e.g., inches, ounces), let me know, and I can adjust the calculator.
  • Cold Process Soap Considerations: The weight calculated is for the liquid batter at pouring. After curing, soap loses water weight (typically 10-20% of the water content), so the final cured soap will weigh less.
