Frequently Asked Questions
About Gigahertz and Megahertz
Gigahertz (GHz)
The gigahertz (GHz) equals 1,000 MHz or 10⁹ Hz. It is the standard unit for modern processor clock speeds, Wi-Fi and 5G frequencies, and microwave communications. Consumer CPUs now operate at 3–6 GHz; 5G networks use bands from 600 MHz to 100 GHz.
GHz frequencies correspond to microwave wavelengths (centimeter to millimeter scale). Microwave ovens operate at 2.45 GHz; Wi-Fi uses 2.4 GHz and 5 GHz; mmWave 5G uses 24–100 GHz. Radar systems span 1–100 GHz depending on application.
Interesting fact: Water molecules resonate at around 22 GHz. Microwave ovens use 2.45 GHz — not the resonant frequency — because it penetrates food more deeply, heating it throughout rather than just at the surface.
Megahertz (MHz)
The megahertz (MHz) equals 1,000,000 Hz and is the dominant frequency unit for FM radio, Wi-Fi, mobile networks, and processor clock speeds. The FM radio band spans 87.5–108 MHz; 2.4 GHz Wi-Fi uses channels in the 2,400–2,500 MHz range.
CPU clock speeds are measured in MHz and GHz: a 1 GHz processor = 1,000 MHz. Memory bus speeds, GPU clocks, and RF transmitters are all specified in MHz. The 4G LTE mobile standard uses frequencies from 700 MHz to 2,600 MHz.
Interesting fact: The first consumer 1 GHz CPU (AMD Athlon) launched in March 2000, reaching what seemed an impossible milestone. Moore's Law had predicted it — and modern CPUs now run at 4,000–6,000 MHz (4–6 GHz).
About Gigahertz to Megahertz Conversion
Converting gigahertz to megahertz is essential across electronics, audio, radio communications, computing, and mechanical engineering. Frequency units span from sub-Hz seismic waves to THz optical signals — each discipline uses the scale most natural to its applications.
Quick reference: 10 GHz = 1e+04 MHz and 1,000 GHz = 1e+06 MHz. Reverse: 1 MHz = 0.001 GHz. Exact factor: 1 GHz = 1000 MHz.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
