Frequently asked questions
What units does this frequency wavelength converter support?
It supports 11 units: Hertz (Hz), Kilohertz (kHz), Megahertz (MHz), Gigahertz (GHz), Terahertz (THz), Wavelength in kilometres (km), Wavelength in metres (m), Wavelength in centimetres (cm), Wavelength in millimetres (mm), Wavelength in micrometres (µm), Wavelength in nanometres (nm).
What is the base unit of frequency wavelength?
The SI reference unit is the hertz (Hz). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
