Key Conclusion (This is a fairly accurate conversion! You can skip it if you find it troublesome!) For "round molds," increasing the size doesn't simply double the volume. The volume increase is mainly due to the increased diameter, with only a small increase in height. Therefore, the volume ratio of adjacent sizes is between 1.4 and 1.8 times. [Baking Principles Collection] http://www.xiachufang.com/board/1126305942716071937/ Using a 4-inch round mold as a baseline, assuming the volume of a 4-inch round mold is 1 unit, it can be seen that from 4 inches to 12 inches, the volume expands more than 16 times, a very significant change. For "upgrades" between adjacent round sizes, the larger the size, the smaller the proportion of "extra" ingredients required for each upgrade. Important Reminder: Heart Shape vs. Round – This is the most crucial practical difference! A heart-shaped mold of the same "inch" has a much smaller actual volume than a round mold. 💡 This means that if a recipe is for an 8-inch round mold and you switch to an 8-inch heart-shaped mold, you only need to use about 65% of the ingredients from the original recipe, otherwise the cake will be too full.

Cake mold conversion: baking principles and steps
Step 1
Key takeaways: ✅ Larger round molds result in more significant volume increases, but not proportionally. ✅ The most accurate method for adjusting cake recipes is to calculate the actual volume ratio. ✅ Heart-shaped molds are approximately 35%-40% smaller than round molds of the same size; please keep this in mind when converting recipes!
