Frequency Wavelength Converter

Convert between hertz, megahertz, gigahertz and calculate wavelength

How to Use

1 Enter a frequency or wavelength value
2 All other units update automatically
3 Wavelength calculated using speed of light (299,792,458 m/s)

Conversion Formulas

Hz → kHz: kHz = Hz ÷ 1000

MHz → GHz: GHz = MHz ÷ 1000

Wavelength = c ÷ f

c = 299,792,458 m/s (speed of light)

FAQ

What is frequency?

Frequency is the number of cycles per second, measured in hertz (Hz). It describes how often a periodic phenomenon repeats.

How are frequency and wavelength related?

Frequency (f) and wavelength (λ) are inversely proportional: λ = c/f where c is the speed of light (299,792,458 m/s).

What is the electromagnetic spectrum?

The electromagnetic spectrum ranges from radio waves (low frequency, long wavelength) to gamma rays (high frequency, short wavelength).
