Frequency Conversions
Frequency measures how many times an event repeats per second, expressed in hertz (Hz). It spans from the slow rotation of mechanical motors (RPM) to the billions of cycles in modern CPU processors (GHz). Frequency conversions are used in electronics, audio engineering, radio communications, signal processing, and computing — any field where periodic signals, oscillations, or rotational speeds are measured.

Frequently Asked Questions — Frequency
How many Hz is 1 GHz?
1 GHz equals 1,000,000,000 Hz (1 billion hertz). Modern computer processors typically run at 3–5 GHz. WiFi networks operate at 2.4 GHz and 5 GHz (or 6 GHz for WiFi 6E).
What is the human hearing frequency range?
Humans can typically hear sounds between 20 Hz (deep bass) and 20,000 Hz (20 kHz, high-pitched treble). The range narrows with age, particularly at high frequencies. Audio equipment is often rated 20 Hz–20 kHz to cover the full audible spectrum.
How do I convert RPM to Hz?
Divide RPM by 60 to get Hz. For example, an engine at 3,000 RPM rotates at 50 Hz (50 full rotations per second). An 8,000 RPM electric motor spins at about 133 Hz.
