What does the prefix "centi" denote in the metric system?

The prefix "centi" in the metric system denotes one hundredth (0.01). This prefix is derived from the Latin word "centum," which means "one hundred." Therefore, when "centi" is used, it signifies a fraction of a unit that is 1/100 of the base unit. For instance, a centimeter (cm) is one-hundredth of a meter, illustrating how "centi" is applied in real measurements. This understanding of metric prefixes is essential in scientific contexts, as they provide clarity and precision in quantifying measurements.
