How to Convert Hertz to Kilohertz

1 hertz = 0.001 kilohertz

Kilohertz = Hertz × 0.001

Example: 48000 Hz × 0.001 = 48 kHz

Reverse Conversion

To convert kilohertz back to hertz:

  • Remember, 1 kilohertz equals 1000 hertz.
  • To convert 48 kHz to Hz, multiply 48 x 1000, resulting in 48000 Hz.

48,000 Hz equals 48 kHz — the standard sampling rate for professional audio and video production (DVD, Blu-ray, broadcast). Slightly higher fidelity than CD.

48000 Hz is also equal to:

  • 0.048 megahertz
  • 2880000 revolution per minute
About these units

Hertz: SI unit of frequency; one cycle (or event) per second. Symbol: Hz = s⁻¹

Kilohertz: SI decimal multiple of hertz; 1 kHz = 1,000 Hz = 10³ Hz

Frequently Asked Questions

How much is 48000 hertz in kilohertz?

48000 hertz equals 48 kilohertz. This is calculated by multiplying 48000 by the conversion factor 0.001.

What does 48000 hertz look like in kilohertz?
