About the units
Kilohertz (kHz)
A kilohertz is 1,000 Hz, common for AM radio and audio.
Hertz (Hz)
One hertz is one cycle per second.
How to use this converter
- Type the number of kilohertz (kHz) in the input box.
- The result in hertz appears instantly — no button needed.
- See the same value in every other frequency unit just below.
- Use “Swap units” to convert hertz back to kilohertz.
When you’ll use the kilohertz to hertz conversion
Converting kilohertz to hertz comes up more often than you might expect — for example when radio and Wi-Fi band settings, motor and fan speeds in rpm, or audio and music production. Type your number once and you get the exact answer plus every related unit, so you don’t need to convert twice.
💡 The factor is exact and easy to remember: 1 kHz = 1,000 Hz.
Watch out for these mix-ups
- rpm counts full revolutions per minute; Hz counts cycles per second (60 rpm = 1 Hz).
- MHz and Mbps sound alike but measure different things.
Tips for better results
- Double-check which system a unit belongs to (for example US vs UK gallons).
- Use the swap button to convert in the opposite direction instantly.
- Bookmark the conversions you use most — each pair has its own page.
Frequently asked questions
How many hertz are in one kilohertz?
