1 and 10 inch cakes are 10 inch in diameter, and one inch is 2.54 cm, so the diameter of 10 inch cakes is 25.4 cm, that is, 2.54x 10=25.4cm.

2, 12 inch is 30.48 cm in diameter. This theoretical value is actually about 30 cm, which is enough for 8 to 15 people. Inches in cake size refers to inches.

At present, the sizes on the market are generally uniform, mainly because the molds produced by mold manufacturers are relatively uniform, which indirectly regulates the size uniformity of cakes. There are six standard sizes of cake shops: 4-6-8-10-12-14. Generally speaking, the measurement of inch/inch/gram/pound can be roughly converted as follows:

4-5 inches (inches), about 250g, about 0.5kg, and the diameter is about10-1cm. It is recommended to eat 1-2 people.

6 inches (inches), about 500 grams, about 1 kg, about 15cm in diameter, recommended for 2-4 people.

8 inches (inches), about 1 kg, about 2 kg, about 20cm in diameter, recommended for 5-8 people.

10 inch (inch), about 1.5 kg, about 3 pounds, and about 25 cm in diameter. It is recommended to eat 9- 12 people.

12 inch (inch), about 2 kg, about 4 kg, about 30cm in diameter, recommended number 13- 18.
