Introduction: The Metric System and Centimeters
The metric system, officially known as the International System of Units (SI), is a decimal system of measurement based on units of ten. The fundamental unit of length in the metric system is the meter (m). Plus, a centimeter (cm) is one-hundredth of a meter (1 cm = 0. That's why, understanding centimeters involves understanding their relationship to meters, and subsequently, to other units of length like millimeters and kilometers. This makes conversions between units incredibly straightforward. 01 m). This article aims to make understanding 20 cm both clear and intuitive.
