Pizza is measured in diameter. To convert it into centimeters, you only need to multiply the inch diameter by 2.54. Pizza is named after its diameter, such as 6-inch pizza, which means the diameter of the pizza is 6 inches. One inch is equal to 2.54 centimeters, so if you want to convert it into centimeters, you only need to multiply the inch diameter by 2.5.
For example, for a 6-inch pizza, multiply 6 by 2.54, and the result is 15.24 centimeters. Of course, pizza is not strictly accurate to the millimeter. Coupled with the invalid pizza edges, the real effective area generally needs to remove the area after the decimal point. For example, the diameter of a 6-inch pizza is 15.24 cm, and the actual effective area is generally 15 cm.
