The main difference between a centi unit and a milli unit lies in their respective magnitudes:
- A centi unit (centi-) is equal to 1/100th or 0.01 of the base unit. For example, 1 centimeter (cm) is equal to 0.01 meters (m).
- A milli unit (milli-) is equal to 1/1,000th or 0.001 of the base unit. For example, 1 millimeter (mm) is equal to 0.001 meters (m).
So, the difference between a centi unit and a milli unit is that a centi unit is 10 times larger than a milli unit. In other words, there are 10 milli units in 1 centi unit.
