How much mixture does your mold need?
Multiply the cavities you will fill by the stated per-cavity volume. Keep a measured fill line separate from nominal capacity.
Count the batch you are making
Use the number of cavities you intend to fill, rather than automatically using the entire set. For example, six 90 mL cavities have a nominal combined volume of 540 mL. That is arithmetic, not a tested recipe yield.
Read the volume label carefully
Our tool uses U.S. fluid ounces: one U.S. fl oz equals 29.5735295625 mL. An ounce of weight is a different measurement. Manufacturer capacities marked “about” remain approximate after conversion; extra decimal places do not improve the underlying specification.
Compare nominal batches, not just cavity count
The source-listed ZK114 holds about 3.1 U.S. fl oz per cavity: six cavities total about 18.6 U.S. fl oz, or 550 mL. Nine ZK115 mini cavities at about 0.6 U.S. fl oz total about 5.4 U.S. fl oz, or 160 mL. More cavities do not necessarily mean more mixture. These are rounded nominal calculations, not tested recipe yields or instructions to fill to the brim.
Treat headroom as a separate instruction
Follow the mold’s fill line and manual. There is no universal percentage that we can assign to every mixture or mold. If you enter an allowance in the calculator, it reduces the nominal fill by your chosen percentage; it does not certify a correct expansion gap.
