How to Convert Megahertz to Kilohertz
The megahertz and kilohertz are both units of frequency. By definition, 1 kilohertz equals exactly 1000000 megahertz. This means to convert megahertz to kilohertz, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 MHz to kilohertz:
We need to convert megahertz to kilohertz
Since 1 kHz = 1000000 MHz, divide by 1000000
5 ÷ 1000000 = 5e-6
5 MHz = 5e-6 kHz

About These Units
Megahertz (MHz)
A megahertz (MHz) equals 1 million hertz. Megahertz measures FM radio (88-108 MHz), WiFi frequencies (2400 MHz, 5000 MHz), and older CPU speeds. Early Pentium processors ran at 60-200 MHz. Television channels use MHz frequencies.
Kilohertz (kHz)
A kilohertz (kHz) equals 1,000 hertz. Kilohertz measures AM radio frequencies (530-1700 kHz), ultrasonic cleaning (20-40 kHz), and audio sample rates (44.1 kHz for CD quality). Human hearing upper limit is about 20 kHz.
