Important to know
Convert between hertz, kilohertz, megahertz and gigahertz.
Negative frequencies are mathematical inputs here; physical frequency is normally nonnegative.
Formula and methodology
Convert to hertz, then divide by the target unit factor: kHz = 1,000 Hz; MHz = 1,000,000 Hz; GHz = 1,000,000,000 Hz.
Example
2.5 MHz equals 2,500 kHz.
