Kilohertz to Hertz Converter
1 kHz equals 1,000 Hz, and 1 Hz equals 0.001 kHz. Enter a value in either box to convert kilohertz to hertz and back. Formula: hertz = value x unit factor (1 rpm = 1/60 Hz; 1 rad/s = 1/(2 pi) Hz).

Formula
hertz = value x unit factor (1 rpm = 1/60 Hz; 1 rad/s = 1/(2 pi) Hz)Understanding Frequency Conversion
Frequency counts how many times something repeats each second; one hertz is one cycle per second. Radio uses kilohertz to gigahertz, computer processors are rated in gigahertz, and engines and turntables use revolutions per minute. Angular velocity in radians per second is related to frequency by a factor of 2 pi, which is why rotating machinery is described in whichever of the three units suits the field.
Tips and Best Practices
- 1Divide rpm by 60 to get hertz.
- 2Multiply hertz by 2 pi to get radians per second.
- 3The concert pitch A above middle C is 440 Hz.
Real-World Example
A record at 33 1/3 rpm turns 0.5556 times each second (0.5556 Hz). A 3 GHz processor ticks 3,000,000,000 times a second.
Common Mistakes to Avoid
- Confusing frequency in Hz with angular frequency in rad/s, a factor of about 6.28.
- Treating rpm as a per-second unit.
- Mixing MHz and GHz when reading CPU or Wi-Fi bands.
How to Use
- Type a number in the Kilohertz box.
- The Hertz result appears instantly; you can also edit the Hertz box to convert backwards.
- Use the swap button to reverse the direction and Copy result to copy the answer.
