The inch is a unit of length in the British imperial and the United States customary systems of measurement. The word inch is derived from the Roman uncia ("twelfth") and is occasionally used to translate analogous units in other measuring systems, which are commonly considered to be derived from the width of the human thumb.

In the past, standards for the precise length of an inch fluctuated, but with the adoption of the international yard in the 1950s and 1960s, the inch has been based on the metric system and defined as exactly 2.54 cm.

Inch is not commonly used internationally so you might find it difficult to convert inch to other units of length. Don't worry, our Calculatorful pool of converters is full of handy tools for you to choose from like Inches to Feet | Feet to Inches.

A centimeter (SI symbol cm) is a length unit in the International System of Units (SI) equal to one-hundredth of a meter, with *centi* being the SI prefix denoting a factor of $\frac{1}{100}$. In the now-deprecated centimeter-gram-second (CGS) unit system, the centimeter was the base unit of length.

Though scientists frequently prefer SI prefixes for factors of ${10}^{3}$, such as milli- and kilo, for many physical quantities, the centimeter remains a practical unit of length for many common measures. A centimeter is roughly the width of an average adult's fingernail.

Inches and centimeters are units of length in different systems. Therefore, to convert between them, we should understand their relationship clearly. The relationship between inch and cm is that one inch is exactly equal to 2.54 cm in the metric system.

1 in= 2.54 cm

In other words, the distance in centimeters is equal to the distance in inches times 2.54 cm.

Distance(cm)= Distance(inch) x 2.54

To convert the values from inches to centimeters, use inches to cm converter in order to find the values easily.
