12 inch cake is 30.48 cm in diameter. In cake making, size is very important, especially in business environment. Different countries or regions may use different units to represent the size of cakes. In China, we usually use centimeters as the unit of length. In the United States and some other countries, the size of cakes is usually expressed in inches.

So this has caused many people to encounter some confusion when converting the cake size. The following is a simple formula that can be used to convert inches into centimeters: 1 inch =2.54 centimeters. Then, if there is a 12 inch cake, we can use the above formula to calculate the diameter of the cake.

First, we convert 12 inch into cm, and get 12 inch x2.54 cm/inch =30.48 cm. Therefore, the diameter of a 12 inch cake is 30.48 cm. Of course, this is only an approximation, because when making cakes, there may be some difference in diameter, or some decorations may slightly increase the diameter of the cakes. However, this formula can help us to quickly and accurately convert between different units, so as to better understand the size of the cake.
