1 kilohertz (kHz) equals how many hertz (Hz)?

Explanation:
Frequency is measured in hertz, which is one cycle per second. The prefix kilo- means 1000, so 1 kilohertz equals 1 × 1000 hertz, or 1000 Hz. In other words, a signal that repeats 1000 times each second has a frequency of 1 kHz. The other numbers represent 900 Hz, 10,000 Hz (10 kHz), and 100 Hz, which are not equal to 1 kHz.
