Frequency Converter

Unit Converters

Hz, kHz, MHz, GHz

Quick Answer

Frequency Converter: Hz, kHz, MHz, GHz. Frequency Converter uses standard unit conversion formulas to compute accurate results instantly.

Kilohertz (kHz)1.0000
Megahertz (MHz)0.001000
Gigahertz (GHz)0.000001000
Wavelength (λ=c/f)300,000.00m
Period (T=1/f)0.001000s
BandVLF

Calculation steps

  1. 1Unit scaling: 1,000.00 Hz ÷ 1000 = 1.0000 kHz; ÷ 10⁶ = 0.001000 MHz; ÷ 10⁹ = 0.000001000 GHz
  2. 2Wavelength: λ = c ÷ f = 3×10⁸ ÷ 1,000.00 = 300,000.00 m
  3. 3Period: T = 1 ÷ f = 1 ÷ 1,000.00 = 0.001000 s

Common frequency reference

RangeApplication
20 Hz – 20 kHzAudible sound
3 kHz – 300 kHzLW/MW radio
3 MHz – 30 MHzShortwave (HF)
87.5 – 108 MHzFM broadcast
300 MHz – 3 GHzUHF / 4G / WiFi
3 GHz – 300 GHzMicrowave / 5G / satellite
Higher frequency means shorter wavelength and more information capacity, but weaker wall penetration — that is why 5G mmWave is fast yet short-ranged, and WiFi 2.4G covers farther than 5G WiFi.
