kHz to MHz Converter
Convert kilohertz (kHz) to megahertz (MHz) instantly. Type a value — the result updates as you type, and the swap button converts the other way.
kHz to MHz formula
MHz = kHz ÷ 1000
1 kilohertz = 0.001 megahertz · 1 megahertz = 1000 kilohertz
To convert kilohertz to megahertz, divide the value by 1000. For example, 1500 kHz:
MHz = 1500 ÷ 1000MHz = 1.5
So 1500 kHz = 1.5 MHz.
Mental math shortcut
This conversion is exact, so there is no need to estimate: just divide by 1,000.

| Megahertz | Kilohertz |
|---|---|
| 0.1 MHz | 100 kHz |
| 0.53 MHz | 530 kHz |
| 1 MHz | 1000 kHz |
| 1.7 MHz | 1700 kHz |
| 10 MHz | 10000 kHz |
About the units
Kilohertz (kHz)
A kilohertz is 1,000 hertz. AM radio and audio sample rates are given in kHz.
Megahertz (MHz)
A megahertz is one million hertz. FM radio and older processors are measured in MHz.
