Hz, rpm, and rad/s — the key frequency units

The hertz (Hz) is the SI unit of frequency and measures cycles per second; kilohertz (kHz), megahertz (MHz), and gigahertz (GHz) are its powers-of-ten multiples (×1,000, ×1,000,000, ×1,000,000,000). They describe audio (Hz/kHz), radio and broadcast (MHz), and Wi-Fi and processor clocks (GHz).

rpm and rad/s describe rotation rather than waves: rpm (revolutions per minute) is a rotational speed, where 60 rpm equals exactly 1 Hz (one revolution per second). rad/s is the angular frequency ω, with ω = 2πf, so 1 Hz equals 2π rad/s ≈ 6.283 rad/s.

Frequently asked questions

How many kHz are in 1 MHz?

1 MHz equals 1000 kHz.

How many kHz are in 2 MHz?

2 MHz equal 2000 kHz.

How do I convert MHz to kHz?

Multiply the frequency in MHz by 1000 to get kHz.

Is the MHz-to-kHz conversion exact?

Yes. Frequency conversions rest on fixed factors (powers of ten for the SI prefixes); the values here are only rounded to two decimal places.

What are these frequency units used for?

Hertz (Hz) is the SI unit of frequency; kilohertz (kHz), megahertz (MHz), and gigahertz (GHz) are its multiples, describing audio, radio, wireless, and processor clocks. rpm measures the rotational speed of motors and drives, and rad/s (angular frequency) is used in physics and control engineering.
