Inch to Centimeter Converter

An inch is a unit of length in the imperial and US customary systems equal to 1/12 of a foot or approximately 2.54 centimeters. It is used for precise measurements of smaller objects.

The inch has ancient origins, possibly derived from the width of a man's thumb. The word comes from the Latin 'uncia' meaning 'twelfth part'. It was standardized in England and later defined internationally as exactly 25.4 millimeters in 1959.

Inches are widely used in the United States for measuring screen sizes, pipe diameters, lumber dimensions, and precision measurements in manufacturing. They're standard for tools, fasteners, and many consumer products in countries using imperial measurements.

A centimeter (cm) is a unit of length in the metric system equal to one-hundredth of a meter (0.01 m). It is widely used for measuring small to medium-sized objects and dimensions.

The centimeter was derived from the meter as part of the metric system's decimal structure, established in 1795. The prefix 'centi-' comes from the Latin word 'centum' meaning 'hundred'. It became popular due to its practical size for everyday measurements.

Centimeters are extensively used worldwide for measuring body dimensions (height, waist size), clothing sizes, small objects, and in medical applications. They're standard in tailoring, carpentry for precise measurements, and in many consumer products specifications.
