How to Convert Kilohertz to Megahertz (kHz to MHz)
Frequency conversions apply to radio stations, Wi-Fi bands and processor speeds. This guide shows how to convert kilohertz into megahertz by hand, with examples and a quick-reference table.
The conversion
To convert kilohertz to megahertz, multiply the value by 0.001. To go the other way, divide by the same number (or multiply by 1,000). For a quick estimate, multiply by about 0.001.
Megahertz = kilohertz × 0.001
Worked examples
- 3 kHz = 0.003 MHz
- 12.5 kHz = 0.0125 MHz
- 75 kHz = 0.075 MHz

| 20 kHz | 0.02 MHz |
| 25 kHz | 0.025 MHz |
| 50 kHz | 0.05 MHz |
| 100 kHz | 0.1 MHz |
| 250 kHz | 0.25 MHz |
| 500 kHz | 0.5 MHz |
| 1,000 kHz | 1 MHz |
Common questions
Is kHz to MHz exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.
How do I convert back?
Use the Megahertz to Kilohertz converter.
Mistakes to avoid
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Multiplying when you should divide
Converting to a smaller unit gives a bigger number, and converting to a larger unit gives a smaller one. If your answer moves the wrong way, you have inverted the factor.
Background
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
