Kilohertz to Megahertz Conversion Table
Common values, ready to copy:
| kilohertz | megahertz |
|---|---|
| 1 kHz | 0.001 MHz |
| 2 kHz | 0.002 MHz |
| 5 kHz | 0.005 MHz |
| 10 kHz | 0.01 MHz |
| 25 kHz | 0.025 MHz |
| 50 kHz | 0.05 MHz |
| 100 kHz | 0.1 MHz |
| 1,000 kHz | 1 MHz |
Formula
megahertz = kilohertz × 0.001
Frequency uses the SI hertz (Hz, cycles per second). 1 kHz = 1,000 Hz; 1 MHz = 1 million Hz; 1 GHz = 1 billion Hz. RPM and BPM are both "cycles per minute": 60 RPM = 1 Hz.
About Kilohertz and Megahertz
Kilohertz (kHz): A thousand hertz; the unit for AM radio frequencies and low-frequency audio. Common uses: AM radio (530-1700 kHz), keyboard scan rates, and the upper end of human audible frequencies.
Megahertz (MHz): A million hertz; the unit for FM radio, older computer clock speeds, and microwave-band wireless. Common uses: FM radio (88-108 MHz), microcontroller clock speeds, ham radio, and some Wi-Fi specifications.
How the conversion works
Frequency uses the SI hertz (Hz, cycles per second). 1 kHz = 1,000 Hz; 1 MHz = 1 million Hz; 1 GHz = 1 billion Hz. RPM and BPM are both "cycles per minute": 60 RPM = 1 Hz.
The exact relationship is megahertz = kilohertz × 0.001, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between kilohertz and megahertz comes up wherever frequency measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
