Often times people are looking for a mold based on the desired weight of the finished chocolate. This information can be used for establishing prices, budgeting expenses, and estimating supply needs. Unfortunately, most mold manufacturers do not list the weight of each piece in their sales descriptions. Thus, you have to do a little math to estimate the weight.
Say for example, a chocolate mold has 6 cavities that are 2" length x 2.5" width x .5" deep. How much will each finished chocolate piece weigh? In order to figure out the answer you will need to know the following calculations:
Cubic Inch = Length x Width x Depth
1 Cubic Inch = 0.554112554 US fluid ounces
1 US fluid ounce = 28.3495231 grams
So, in our example:
Cubic Inch = 2 x 2.5 x .5 = 2.5 cubic inches
2.5 cubic inches x .5541 = 1.385 US fluid ounces
1.385 US fluid ounces x 28.3495 = 39.27 grams
Therefore, one mold would make 6 chocolates that weigh approximately 39 grams.
