How to Convert Kilohertz to Hertz (kHz to Hz)
Frequency conversions apply to radio stations, Wi-Fi bands and processor speeds. This guide shows how to convert kilohertz into hertz by hand, with examples and a quick-reference table.
The conversion
To convert kilohertz to hertz, multiply the value by 1,000. To go the other way, divide by the same number (or multiply by 0.001). For a quick estimate, multiply by about 1,000.
Hertz = kilohertz × 1,000
Worked examples
- 3 kHz = 3,000 Hz
- 12.5 kHz = 12,500 Hz
- 75 kHz = 75,000 Hz

Common questions
Is kHz to Hz exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.

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.
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.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Background
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
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.
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.
