Frequently Asked Questions
About Megahertz and Revolutions/Second
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).
Revolutions/Second (rps)
Revolutions per second (rps) is the rotational frequency equivalent of hertz for mechanical systems. Since one complete revolution per second = 1 Hz, rps and Hz are numerically identical for periodic motion, though rps implies mechanical rotation while Hz implies general oscillation.
RPS is used in precision mechanical engineering, robotics, and motor control where per-second rates are more convenient than per-minute. A hard drive at 7,200 RPM rotates at exactly 120 rps.
Interesting fact: The relationship rps = Hz is not coincidental — both describe one complete cycle per second. Angular velocity in rad/s = 2π × rps, connecting rotational mechanics directly to wave physics through the same fundamental concept of cyclic repetition.
About Megahertz to Revolutions/Second Conversion
Converting megahertz to revolutions/second 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+07 rps and 1,000 MHz = 1e+09 rps. Reverse: 1 rps = 1.0000e-6 MHz. Exact factor: 1 MHz = 1e+06 rps.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
