About this tool
The inch is an imperial unit of length still used in the United States for height, screen sizes, and tools and hardware measurements. It was standardized in 1959 as exactly 2.54 centimeters.
The centimeter is the metric unit of length used for the same everyday purposes in nearly every other country, from clothing sizes to furniture dimensions.
