20 Centimeters to Millimeters equals 200 mm.

Converting 20 cm to millimeters (mm) involves understanding the relationship between centimeters and millimeters in the metric system. In this system, 1 centimeter (cm) is equal to 10 millimeters (mm). Therefore, to convert centimeters to millimeters, you multiply the number of centimeters by 10.

In this case, you have 20 cm that you want to convert to mm. Using the conversion factor mentioned earlier, you would calculate the conversion as follows: 20 cm x 10 mm/cm = 200 mm. Thus, 20 cm is equal to 200 millimeters. The multiplication by 10 is straightforward because of the base-10 nature of the metric system, making it easy to shift between units of length such as cm to mm by simply moving the decimal point. In this calculation, you're essentially multiplying 20 by 10, which gives you 200, and that's why 20 cm equals 200 mm.
