Unit prefixes are standard prefixes used in the metric system and other measurement systems to denote multiples or fractions of units. These prefixes help simplify the expression of large or small quantities by providing a concise way to represent these amounts. For example, instead of saying "1000 meters," one might say "1 kilometer," where "kilo-" is the prefix that indicates a factor of 1000.
