Use the following equations to convert kHz, MHz, and meters.

To convert MHz to kHz, multiply by 1,000. For example:

9.62 MHz ¥ 1000 = 9,620 kHz

To convert kHz to MHz, divide by 1,000. For example:

2780 kHz ³ 1000 = 2.780 MHz

To convert MHz to meters, divide 300 by the number of MHz. For example:

300 ³ 7.1 MHz = 42.25 meters

To convert meters to MHz, divide 300 by the number of meters. For example:

300 ³ 42.25 meters = 7.1 MHz
