Megahertz (MHz)
The megahertz, symbol MHz, equals one million hertz and is commonly used to describe radio frequencies, microprocessor clock speeds, and wireless communications. As technology advanced from kilohertz applications, the 20th century saw the introduction of megahertz, providing a practical scale for high-frequency signals. It is especially relevant in radio, television, mobile networks, and computing. The unit ensures clarity and precision when dealing with millions of cycles per second, making it indispensable for engineers, technicians, and hobbyists alike.
Hertz (Hz)
The hertz (Hz) is the internationally recognized unit for measuring frequency, representing one cycle occurring each second. The unit honors Heinrich Hertz, a pioneering German physicist who, in the late 1800s, experimentally confirmed the presence of electromagnetic waves. Since its adoption, the hertz has served as the fundamental standard for tracking repeating events in fields such as physics, engineering, radio, and telecommunications. Its use streamlines the measurement and comparison of various oscillating phenomena, ensuring consistency across scientific and technical disciplines.
