About this

A single linear centimeter is exactly 10 millimeters long. Because area applies to both width and height, you must square the linear multiplier (10 × 10). This means that exactly 100 square millimeters fit perfectly inside a single square centimeter. Simply divide by 100 to scale up your metric dimensions.
