The most common unit used to measure frequency is hertz (Hz), which refers to cycles per second; however, there are some other ways to measure frequency, such as revolutions per minute (RPM) for a motor or beats per minute (BPM) for a person's heartbeat.
Its a sound measurement. kHz is an abbreviation for kilohertz - a unit of measurement of wave frequency (alternating current or electromagnetic), also known as cycles per secoâ¦nd. One kilohertz equals 1,000 hertz (Hz), or 1,000 cycles per second. This unit is also used in measurements of signal bandwidth.
