Relationship Between Hertz and Megahertz
The conversion between hertz and megahertz is based on the metric system where 1 megahertz equals 1,000,000 hertz.
1 MHz = 1,000,000 Hz
Therefore,
1 Hz = 0.000001 MHz
To convert hertz to megahertz, we divide the value in hertz by 1,000,000 (or multiply by 0.000001).
For example, 1,000,000 Hz equals 1 MHz, and 5,000,000 Hz equals 5 MHz.
Hertz
What is a Hertz (Hz)?
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), defined as one cycle per second. It is named after Heinrich Rudolf Hertz, a German physicist who made important contributions to the study of electromagnetism. The hertz is used to measure periodic events, such as oscillations, vibrations, and waves.
History and Origin
The hertz was adopted as the unit of frequency by the International Electrotechnical Commission (IEC) in 1930 and later by the General Conference on Weights and Measures (CGPM) in 1960. It replaced the older unit 'cycles per second' (cps). The unit is named after Heinrich Rudolf Hertz (1857-1894), who was the first to conclusively prove the existence of electromagnetic waves.
Common Applications
- Audio frequencies: Human hearing range is approximately 20 Hz to 20,000 Hz (20 kHz)
- Radio frequencies: AM radio (530-1700 kHz), FM radio (88-108 MHz)
- Electrical power: Standard AC power is 50 Hz (Europe, Asia) or 60 Hz (Americas)
- Computer processors: CPU clock speeds measured in GHz (billions of hertz)
- Musical notes: A4 (concert pitch) is 440 Hz
- Medical imaging: Ultrasound frequencies range from 2-18 MHz
- Wireless communication: WiFi (2.4 GHz, 5 GHz), Bluetooth (2.4 GHz)
- Scientific research: Various frequencies used in spectroscopy, NMR, and other fields
Megahertz
What is a Megahertz (MHz)?
A megahertz (symbol: MHz) is a unit of frequency equal to 1,000,000 hertz (1 million hertz). The prefix 'mega-' means one million, making the megahertz a convenient unit for measuring frequencies in the millions of hertz range. Megahertz is commonly used for radio frequencies, computer processors, and other high-frequency applications.
Common Uses
- FM radio: Broadcast frequencies range from 88 MHz to 108 MHz
- Computer processors: CPU clock speeds (though modern CPUs are now measured in GHz)
- Radio communication: Two-way radios, walkie-talkies operate in MHz range
- Medical imaging: Ultrasound equipment typically uses frequencies from 2-18 MHz
- Wireless communication: Some older wireless standards operate in MHz
- Television broadcasting: VHF and UHF channels use MHz frequencies
- Amateur radio: HAM radio operators use various MHz frequency bands
- Scientific instruments: Oscilloscopes, signal generators, spectrum analyzers
Conversion Context
Megahertz is particularly useful when dealing with frequencies that would be cumbersome to express in hertz or kilohertz. For example, expressing 100,000,000 Hz as 100 MHz is much more readable. The megahertz unit bridges the gap between kilohertz (for lower frequencies) and gigahertz (for higher frequencies).
