Short background on the units used in this conversion.
Wavelength in metres is a reciprocal unit: frequency in hertz equals the speed of light divided by wavelength. At 1 metre, frequency is 299,792,458 hertz.
Metre-scale wavelengths describe long-wave radio, geophysical signals, and introductory physics problems linking f and λ.
kHz = m × 299,792.458m = kHz × 299,792.458, using the same exact factors as this converter.
