What is the abbreviation and value of the prefix representing one thousand?

• A. k, 1,000
• B. K, 1,000
• C. k, 10,000
• D. c, 1,000

Answer: (A)

In the metric system, prefixes multiply a base unit by powers of ten. For one thousand, the prefix is kilo-, and it is written with a lowercase look: k. This symbol represents 10^3, which equals 1,000. It’s used in common units like kilometer (km) and kilogram (kg). The uppercase K isn’t used for the thousand prefix; it stands for kelvin, a temperature unit, so it wouldn’t represent 10^3. That makes the lowercase k paired with 1,000 the correct match.
