How to Convert Gigahertz to Kilohertz (GHz to kHz)
Frequency conversions apply to radio stations, Wi-Fi bands and processor speeds. This guide shows how to convert gigahertz into kilohertz by hand, with examples and a quick-reference table.
The conversion
To convert gigahertz to kilohertz, multiply the value by 1,000,000. To go the other way, divide by the same number (or multiply by 1.000000e-06). For a quick estimate, multiply by about 1,000,000.
Kilohertz = gigahertz × 1,000,000
Worked examples
- 3 GHz = 3,000,000 kHz
- 12.5 GHz = 12,500,000 kHz
- 75 GHz = 75,000,000 kHz

| 100 GHz | 100,000,000 kHz |
| 250 GHz | 250,000,000 kHz |
| 500 GHz | 500,000,000 kHz |
| 1,000 GHz | 1,000,000,000 kHz |
Common questions
Is GHz to kHz 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 Kilohertz to Gigahertz 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.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
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
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.
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.
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
