Frequency Converter — Electronics and audio frequency converter for Hertz, kHz, MHz, GHz plus rotational RPM and RPS used for CPUs, radio, and motors.
1,000 Revolutions per minute = 16.6667 Hertz

A frequency converter moves between hertz (cycles per second), its common multiples (kHz, MHz, GHz), and rotational units (revolutions per minute and per second). Frequency is fundamental in electronics, telecommunications, audio, and mechanical engineering: CPUs run at GHz clock rates, radio stations at MHz carrier frequencies, audio is captured in Hz ranges matching human hearing, and engines spin at thousands of RPM. Being able to translate cleanly between these units helps when reading data sheets, tuning radios, sizing motors, or working on physics problems.
Formula
1 kHz = 10³ Hz. 1 MHz = 10⁶ Hz. 1 GHz = 10⁹ Hz. RPM = Hz × 60. RPS = Hz.Frequency conversions sneak into your life in surprisingly varied moments. You're buying a CPU and the spec says 3.8 GHz turbo — but what does that actually mean compared to your old 2.4 GHz laptop, and is the marketing GHz number even meaningful any more (it isn't, mostly). You're configuring a WiFi router and have to choose between 2.4 GHz (longer range, slower, crowded) and 5 GHz (shorter range, faster, cleaner). You're shopping for an inverter or imported appliance and need to know if it runs on 50 Hz (Pakistan, Europe, most of Asia) or 60 Hz (US, parts of Japan) — because a 60 Hz US fridge plugged into 50 Hz Pakistani mains will run 17 percent slower and overheat over time. You're a musician tuning an instrument to A440 (440 Hz, the international standard pitch). Or you're an engineer doing vibration analysis on a motor and need to translate RPM to Hz by dividing by 60. The hertz (one cycle per second) is the universal base; kHz, MHz, GHz are just SI multiples of a thousand. Honest take: when buying any imported electronic appliance from Saudi Arabia, Dubai, or the US, check the input frequency spec on the back — 50/60 Hz dual-frequency means it works anywhere; 60 Hz only means you'll need a frequency converter to use it on Pakistani mains, and those cost more than most appliances.

Hertz (Hz) is defined as one complete cycle per second. The SI prefixes k, M, G scale by powers of 1,000 (strictly 10³, 10⁶, 10⁹). Rotational speeds are usually expressed in RPM (revolutions per minute) because minute-scale numbers are more intuitive for machinery — 6,000 RPM sounds right for a car engine, while 100 Hz does not. Multiply Hz by 60 to get RPM, or divide RPM by 60 to get Hz.

Human hearing: ~20 Hz to 20 kHz in young ears.
FM radio stations broadcast in 87.5–108 MHz; AM in 535–1,705 kHz.
A modern smartphone processor clocks at ~3 GHz (3,000,000,000 cycles per second).
5G mobile signals operate in the 3–40 GHz range; Wi-Fi routers at 2.4 GHz and 5 GHz.
A 3.5 GHz CPU clock cycles 3.5 billion times per second — each cycle potentially executing part of an instruction.
The musical note A4 (middle A) has a frequency of 440 Hz — the international tuning standard used by orchestras.
An engine spinning at 6,000 RPM is oscillating at 100 Hz — useful for vibration analysis and resonance design.
FM radio stations broadcast at 87.5 to 108 MHz in most countries, with each station separated by 0.1 MHz.
A 50 Hz electrical grid (used in Pakistan, Europe, Asia) cycles 50 times a second; the US grid runs at 60 Hz.
Wi-Fi 6 operates on 2.4 GHz and 5 GHz bands, and newer Wi-Fi 6E adds 6 GHz — different bands trade range for speed.
