Final answer:
The conversion factor from centimeters to millimeters is 10; to convert cm to mm, multiply by 10, and to convert mm to cm, divide by 10.
Step-by-step explanation:
The conversion factor from centimeters (cm) to millimeters (mm) is 10. This means that there are 10 millimeters in 1 centimeter. To convert centimeters to millimeters, you multiply the number of centimeters by 10. For example, to convert 8 cm to mm, you would perform the following calculation: 8 cm × 10 = 80 mm. Conversely, if you need to convert from millimeters to centimeters, you divide the number of millimeters by 10. For instance, converting 2000 mm to centimeters would involve dividing 2000 by 10, giving you an answer of 200 cm.
