Why Converting 11 Inches in CM Matters

On the other hand, a centimeter is a metric unit of length. It is used almost everywhere else in the world. A centimeter is one-hundredth of a meter and is shorter than an inch So, when you need to convert from inches to centimeters, you’re basically switching between two systems of measuring length.
