Answer:

How do you convert cm into MM?

Multiply the centimeter value by 10.

1 - The "millimeter" is a smaller unit than the "centimeter," even though both are derived from the basic "meter." When you convert any larger metric unit to a smaller one, you must multiply the original value.

2 - Example: 58.75 cm * 10 = 587.5 mm.
