Hz is the acronym for Hertz.

The unit of measurement for frequency in the International System of Units (SI). Hertz is used to quantify how many cycles or oscillations of a periodic waveform occur in one second. In simpler terms, it measures how many times something repeats within one second.

For example:

  • 1 Hertz (1 Hz) means one cycle or oscillation per second.
  • 10 Hertz (10 Hz) indicates ten cycles in one second.
  • 1,000 Hertz (1 kHz or kilohertz) means one thousand cycles per second.
  • 1,000,000 Hertz (1 MHz or megahertz) corresponds to one million cycles per second.
  • 1,000,000,000 Hertz (1 GHz or gigahertz) signifies one billion cycles per second.

Hertz is commonly used to express the frequency of various phenomena, including:

  1. Electrical Signals: In electronics and telecommunications, Hertz is used to specify the frequency of signals, such as radio waves, audio signals, and clock frequencies in digital circuits.
  2. Sound: In audio, Hertz represents the frequency of sound waves, with lower Hertz values corresponding to lower-pitched sounds and higher values indicating higher-pitched sounds.
  3. Waveforms: In physics and engineering, Hertz describes the frequency of oscillatory or wave-like phenomena, including electromagnetic waves, mechanical vibrations, and more.
  4. CPU Clock Speed: In computing, Hertz measures the clock speed of central processing units (CPUs) and other components, indicating how many cycles per second the processor can execute.
  • Abbreviation: Hz
