Which metric prefix represents 0.1?

The metric prefix that represents 0.1 is indeed deci. The prefix "deci-" is derived from the Latin word "decimus," meaning "tenth." In the metric system, each prefix corresponds to a power of ten. Specifically, "deci-" denotes one-tenth, or 0.1. For example, one decimeter (dm) is equal to 0.1 meters.

Understanding the context of metric prefixes helps clarify this distinction. Other prefixes refer to different values: "milli-" represents one-thousandth (0.001), "centi-" signifies one-hundredth (0.01), and "kilo-" indicates one thousand (1,000). This system allows for easy conversion and understanding of measurements in various scientific and mathematical applications. Thus, "deci-" as a representation of 0.1 is accurate within the framework of the metric system.
