One kilohertz is equal to:

• A. 1,000 hertz
• B. 1,000,000 hertz
• C. 100 hertz
• D. 10 hertz

Answer: (A)

One kilohertz is defined as one thousand hertz. The term "kilo" is a metric prefix that denotes a factor of one thousand (10^3). Therefore, when you see "kilo" associated with hertz, it specifically indicates that it is 1,000 times the base unit, which is hertz itself. This understanding is crucial in various fields, including telecommunications and broadcasting, where frequency measurements are common. However, hertz is the standard unit of frequency, representing cycles per second, and recognizing this relationship helps when dealing with different frequency scales. Other options suggest incorrect conversions of frequencies. For example, one million hertz would be a megahertz, while 100 hertz and 10 hertz are both far less than one kilohertz. Understanding how metric prefixes operate is essential in accurately interpreting and converting frequency measurements.
