Quick Answer
Formula: Megahertz = Hertz × 1.0000e-6
Multiply any hertz value by 1.0000e-6 to get megahertz.
Reverse: Hertz = Megahertz × 1e+06

Frequently Asked Questions
About Hertz and Megahertz
Hertz (Hz)
The hertz (Hz) is the SI unit of frequency, defined as one cycle per second. It was named after Heinrich Rudolf Hertz, the German physicist who first conclusively proved the existence of electromagnetic waves in 1887–1888. The unit was adopted by the General Conference on Weights and Measures in 1960.
Hertz describes the frequency of everything from sound waves (human hearing: 20–20,000 Hz) to AC power (50 or 60 Hz) to radio waves and processor clocks. A standard A4 musical note vibrates at exactly 440 Hz.
Interesting fact: Heinrich Hertz reportedly said his discovery of radio waves would have no practical use. Within a decade, Marconi used them to transmit the first transatlantic radio signal. Hertz died at 36, never knowing the technology named after him would transform civilization.
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 Hertz to Megahertz Conversion
Converting hertz 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 Hz = 1.0000e-5 MHz and 1,000 Hz = 0.001 MHz. Reverse: 1 MHz = 1e+06 Hz. Exact factor: 1 Hz = 1.0000e-6 MHz.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
