Frequency Converter

Frequency is a fundamental concept in physics and engineering that represents the number of occurrences of a repeating event per unit of time. In the context of electrical signals, frequency refers to the number of cycles or oscillations completed by an alternating current (AC) or waveform in one second.

Understanding frequency and its different units is crucial for effectively utilizing different frequency tools. In this article, we will explore the concept of frequency and provide definitions and conversion factors for the most commonly used frequency units.

  • Hertz (Hz): The hertz is the unit of frequency in the International System of Units, equivalent to one cycle per second. The hertz is an SI derived unit whose expression in terms of SI base units is s⁻¹, meaning that one hertz is the reciprocal of one second.
    Conversion Factor: 1 Hz = 1 Hz (Base Unit)

  • Kilohertz (kHz): Kilohertz represents one thousand cycles per second.
    Conversion Factor: 1 kHz = 1,000 Hz

  • Megahertz (MHz): Megahertz represents one million cycles per second.
    Conversion Factor: 1 MHz = 1,000,000 Hz

  • Gigahertz (GHz): Gigahertz represents one billion cycles per second.
    Conversion Factor: 1 GHz = 1,000,000,000 Hz

  • Revolutions/Second (rev/s): Revolutions per second represent the number of complete rotations around a fixed axis in one second.
    Conversion Factor: 1 rev/s = 1 Hz

  • Revolutions/Minute (rev/min): Revolutions per minute represent the number of complete rotations around a fixed axis in one minute.
    Conversion Factor: 1 rev/min = 1/60 rev/s = 1/60 Hz

  • Degrees/Second (°/s): Degrees per second represent the angular displacement in degrees per second.
    Conversion Factor: 1°/s = 1/360 Hz

  • Degrees/Minute (°/min): Degrees per minute represent the angular displacement in degrees per minute.
    Conversion Factor: 1 °/min = 1/60 °/s = 1/21600 Hz

  • Radians/Second (rad/s): Radians per second represent the angular displacement in radians per second.
    Conversion Factor: 1 rad/s = 1/(2π) Hz = 0.159155 Hz

  • Radians/Minute (rad/min): Radians per minute represent the angular displacement in radians per minute.
    Conversion Factor: 1 rad/min = 1/60 rad/s = 0.00265258 Hz

  • RPM: RPM is another name for Revolutions Per Minute and represents the number of complete rotations around a fixed axis in one minute.
    Conversion Factor: 1 RPM = 1/60 Hz

Frequency is a fundamental parameter used to describe the oscillatory nature of electrical signals. Understanding the different units of frequency, such as gigahertz, megahertz, kilohertz, hertz, revolutions per minute, degrees per minute, radians per minute, and their respective conversion factors, is crucial for utilizing frequency tools effectively. By mastering these units, you will have the knowledge and tools to control and manipulate the frequency of electrical signals to meet the specific needs of various applications.
