How to Convert Kilohertz to Gigahertz (kHz to GHz)
Frequency conversions apply to radio stations, Wi-Fi bands and processor speeds. This guide shows how to convert kilohertz into gigahertz by hand, with examples and a quick-reference table.
The conversion
To convert kilohertz to gigahertz, multiply the value by 1.000000e-06. To go the other way, divide by the same number (or multiply by 1,000,000). Because the factor is tiny, scientific notation keeps the numbers manageable.
Gigahertz = kilohertz × 1.000000e-06
Worked examples
- 3 kHz = 3.000000e-6 GHz
- 12.5 kHz = 1.250000e-5 GHz
- 75 kHz = 7.500000e-5 GHz

Mistakes to avoid
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.
Rounding the factor too early
Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.
Background
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.
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.
