How to Calculate Centimeters Into Inches

Converting inches to centimeters is a straightforward process.

When measuring lengths, it is sometimes necessary to convert between inches and centimeters. Centimeters are a metric length unit used around the world except in the United States, Liberia and Myanmar. One centimeter equals 0.3937 inches. Inches are often used for larger measurements, while centimeters are used for shorter items and in cases where accuracy is very important. Centimeters provide a more precise measurement, as the increments within a centimeter (millimeters) are smaller than the increments within an inch.
