Hz

Hertz

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.
