Kilohertz to Hertz Converter

One Kilohertz equals 1000 Hertz (1 kHz = 1000 Hz). Multiply a Kilohertz value by 1000 to get the equivalent in Hertz. The calculator is above; the formula and worked examples are below.

Formula

How to Convert Manually

Use these steps to convert Kilohertz values to Hertz without the calculator.

  1. Write down the value in Kilohertz (kHz) that you want to convert.
  2. Multiply that value by 1000.
  3. For example, 10 Kilohertz × 1000 = 10000 Hertz.
  4. Label the result as Hertz (Hz).

About Kilohertz and Hertz

The kilohertz is 1,000 hertz. AM radio frequencies, audio sample rates (44.1 kHz), and ultrasound run in the kilohertz range. The hertz is the SI derived unit of frequency: one cycle per second, named after Heinrich Hertz. Sound pitch, mains electricity (50/60 Hz), and display refresh all measure in hertz. One Kilohertz equals 1000 Hertz (1 kHz = 1000 Hz). Kilohertz is used in AM radio tuning and in audio sample rates. Hertz is used in audio pitch and tuning.

Precision and Rounding:Frequency conversions are exact decimal shifts except rpm and rps, which involve the factor 60. Audio and radio work round to convenient figures; clock signals, tuning, and rotating machinery balancing need the unrounded value.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
