A length of 24 centimeters is equal to 9.45 inches. This is roughly equal to the diameter of a basketball or the height of a tiny toy poodle.
The word "inch" derives from the Latin word "uncia," which means "one-twelfth." In this case, an inch is 1/12 of a foot. The precise length of an inch has varied considerably throughout its history, from its earliest appearances in the Middle Ages as well as in different geographic areas. The modern inch was officially standardized on July 1, 1959, in a six-nation international agreement for the standardization of the yard and the pound.
