What is the role of the "Milli" prefix in the metric system?

The "Milli" prefix in the metric system designates a factor of one-thousandth of the base unit. In practical terms, this means that when "Milli" is used with a base unit, it indicates that you have one part out of a thousand parts of that unit. For example, one millimeter (mm) is one-thousandth of a meter (m), and one milliliter (mL) is one-thousandth of a liter (L). This prefix is essential in measurements, particularly in scientific and medical contexts, where precise values are crucial, allowing healthcare professionals to communicate effectively and ensure accurate dosing and measurements. The understanding of prefixes like "Milli" helps to standardize communication across various disciplines.
