What does "kilo" mean?

The term "kilo" originates from the Greek word "chilioi," meaning "a thousand." In the metric system, "kilo" is a prefix used to denote a factor of 1,000. For example, a kilogram (kg) is equal to 1,000 grams, and a kilometer (km) is equal to 1,000 meters. This understanding of "kilo" as representing one thousand is essential when dealing with measurements and calculations in both scientific contexts and everyday life, as it allows for clear communication about quantities and conversions. Therefore, in this context, selecting the meaning of kilo as one thousand is accurate and reflects its established use in the metric system.
