Frequency Conversion Formulas

  • Hertz to
    • Kilohertz (kHz) = Hertz (Hz) / 1000
    • Megahertz (MHz) = Hertz (Hz) / 1,000,000
    • Gigahertz (GHz) = Hertz (Hz) / 1,000,000,000
  • Kilohertz to
    • Hertz (Hz) = Kilohertz (kHz) × 1000
    • Megahertz (MHz) = Kilohertz (kHz) / 1000
    • Gigahertz (GHz) = Kilohertz (kHz) / 1,000,000
  • Megahertz to
    • Hertz (Hz) = Megahertz (MHz) × 1,000,000
    • Kilohertz (kHz) = Megahertz (MHz) × 1000
    • Gigahertz (GHz) = Megahertz (MHz) / 1000
  • Gigahertz to
    • Hertz (Hz) = Gigahertz (GHz) × 1,000,000,000
    • Kilohertz (kHz) = Gigahertz (GHz) × 1,000,000
    • Megahertz (MHz) = Gigahertz (GHz) × 1000

Conversions

  • 1 Hz = 0.001 kHz = 0.000001 MHz = 10-9 GHz
  • 1 kHz = 1000 Hz = 0.001 MHz = 0.000001 GHz
  • 1 MHz = 1000000 Hz = 1000 kHz = 0.001 GHz
  • 1 GHz = 109 Hz = 1000000kHz =1000 MHz
