Frequently Asked Questions
About Megahertz and Kilohertz
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).
Kilohertz (kHz)
The kilohertz (kHz) equals 1,000 Hz and is the standard frequency unit for AM radio, audio signals, and early computing. The AM radio band spans 530–1,700 kHz; human speech occupies roughly 100–8,000 Hz, and telephone systems originally targeted 300–3,400 Hz.
Kilohertz frequencies are used in ultrasound cleaning (20–40 kHz), sonar (1–500 kHz), AM broadcasting (530–1,710 kHz), and audio sampling rates (44.1 kHz for CD audio). Early microprocessors operated in the low MHz range, making kHz relevant to 1970s computing history.
Interesting fact: The 44.1 kHz audio sampling rate (CD standard) was chosen partly because it fit within the bandwidth of a modified video recorder — the original storage medium for digital audio masters in the late 1970s.
About Megahertz to Kilohertz Conversion
Converting megahertz to kilohertz 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 MHz = 1e+04 kHz and 1,000 MHz = 1e+06 kHz. Reverse: 1 kHz = 0.001 MHz. Exact factor: 1 MHz = 1000 kHz.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
