Frequency Converter

Convert Hz, kHz, MHz, GHz, THz, rpm and BPM instantly.

The Frequency Converter moves between hertz and its multiples — kilohertz, megahertz, gigahertz and terahertz — plus the two 'per minute' units people meet in the real world: rpm for rotating machinery and BPM for music.

Radio, Wi-Fi, processors and oscilloscopes live in the SI units: FM radio is around 100 MHz, Wi-Fi at 2.4 or 5 GHz, a CPU at several gigahertz. Mechanical and musical contexts flip to revolutions or beats per minute — a motor spinning at 3,000 rpm is turning 50 times per second (50 Hz), and a 120-BPM song has two beats per second.

The conversion between cycles-per-second and cycles-per-minute is exact (divide by 60), and every SI multiple is a clean power of 10. All conversions happen locally in your browser.

1 Hz = 0.001 kHz

1 Hz = 0.001 kHz

1 kHz = 1,000 Hz

How to use the Frequency Converter

  1. Type the frequency value.
  2. Choose the from-unit (Hz, kHz, MHz, GHz, THz, rpm, BPM).
  3. Choose the to-unit.
  4. Read the converted value and the exact rate.
  5. Swap to convert the other way.

Frequently asked questions

How do I convert MHz to GHz?

Divide by 1,000: 2,400 MHz = 2.4 GHz. Wi-Fi bands illustrate it perfectly — '2.4 GHz' and '5 GHz' are the same as 2,400 MHz and 5,000 MHz, which is how many channel lists label them.

How many Hz is 60 rpm?

One hertz is one cycle per second, so divide rpm by 60: 3,000 rpm = 50 Hz. This is the conversion behind AC power (50/60 Hz grids) and electric motor ratings.

Is BPM the same as rpm?

Structurally yes — both are events per minute. A song at 120 BPM has 120 beats per minute = 2 Hz. The converter treats them as the same unit class so musicians can check the math behind tempo.
