How many inches is a foot and how many centimeters is an inch?

1 foot is equal to 10 inch, and 1 inch is about 3.33 centimeters (cm).

A ruler is a unit of length, which is called "city ruler" in China (three feet equals one meter in modern times) and "ruler" in Britain. Sometimes we also call the tools for measuring length rulers, such as "bamboo ruler" and "steel ruler".

Sometimes we also call things like rulers "rulers", such as iron (a weapon used by ancient knights to fight) and rings (a tool used by religious places or educational institutions to punish students and make them more pious and diligent).

"Inch" is a traditional unit of length in China, which is expressed in decimal system by "ruler" and "ruler" (10 inch = 1 ruler,1ruler = 1 ruler). In Korea, it is used to indicate the number of relatives, for example, 1 inch indicates the relationship between two generations.

The laws of Hong Kong follow the ancient system (1 inch = 3.33cm), but this unit in Hong Kong hardly uses it, and only uses "inch" (1 inch = 2.54cm) and "centimeter". "inch" usually means "inch"
