1 megahertz = 1000 kilohertz
1 kilohertz = 0.001 megahertz
megahertz to kilohertz table
| megahertz (MHz) | kilohertz (kHz) |
|---|---|
| 0.5 | 500 |
| 1 | 1000 |
| 2 | 2000 |
| 5 | 5000 |
| 10 | 10000 |

| 100 | 100000 |
| 500 | 500000 |
| 1000 | 1000000 |
Formula
kilohertz = megahertz × 1000.
Example
10 megahertz = 10000 kilohertz.
What is a megahertz?
A megahertz (MHz) is 1,000,000 Hz.
What is a kilohertz?
A kilohertz (kHz) is 1,000 Hz.
Real-world reference points
Mains power hums at 50/60 Hz; concert pitch A is 440 Hz; CPUs run in the GHz range.
| Reference | megahertz | kilohertz |
|---|---|---|
| Mains electricity (50 Hz regions) | 0.00005 MHz | 0.05 kHz |
| Concert pitch A4 | 0.00044 MHz | 0.44 kHz |
| FM radio (~100 MHz) | 100 MHz | 100,000 kHz |
| Modern CPU (3.5 GHz) | 3,500 MHz | 3,500,000 kHz |
Mistakes to avoid with frequency conversions
- Confusing MHz with Mbps — clock frequency and data throughput are different things.
- Assuming higher GHz always means faster: per-clock work and core counts matter as much.
- Mixing 50 Hz and 60 Hz appliance ratings across regions — motors and clocks care.
