What does the prefix "kilo" represent in powers of ten?

• A. 10^3
• B. 10^6
• C. 10^9
• D. 10^12

Answer: (A)

The prefix "kilo" is derived from the Greek word "khilioi," meaning one thousand. In the International System of Units (SI), "kilo" corresponds to a factor of 1,000, which can be expressed in exponential form as 10 to the power of 3. This means that when you see "kilo" in front of a unit—like kilogram (kg) or kilometer (km)—it indicates a multiplication by 1,000 of that unit. For example, there are 1,000 grams in a kilogram, and there are 1,000 meters in a kilometer. Therefore, the correct representation of "kilo" in powers of ten is indeed 10^3.
