| A radio band is a group of frequencies which are all described by a given characteristic, such as the purpose of the band (Aircraft Bands), a given wavelength (120 meter band) or a given frequency range. For example, amateur radio operators generally refer to frequencies according to their wavelength, with the 19-meter band containing the range of frequencies with waves about 19 meters long. The frequencies are measured in either kilohertz (kHz) or megahertz (MHz).
You can use the following equations to convert between kHz, MHz and meters.
- To convert MHz to kHz, multiply by 1,000. For example:
9.62 MHz x 1000 = 9620 kHz
- To convert kHz to MHz, divide by 1,000. For example:
2780 kHz divided by 1000 = 2.780 MHz
- To convert MHz to meters, divide 300 by the number of MHz. For example:
300 divided by 7.1 MHz = 42.25 meters
- To convert meters to MHz, divide 300 by the number of meters. For example:
300 divided by 42.25 meters = 7.1 MHz
