Fill the mold with water and then pour that water into a measuring cup. Multiply the number of fluid ounces of water by 1.8 to get the total cubic inches of the mold. For example, if your mold holds 12 ounces of water, 12 X 1.8 = 21.6 cubic inches.

Thereof, how do you calculate lye for soap?

Divide the amount of lye by 0.3 and then subtract the amount of lye from the result.

  2. (Amount of Lye) ÷ 0.3 = (Total Weight of Lye Water Solution)
  3. (Total Weight of Lye Water Solution) − (Amount of Lye) = (Amount of Water)
