About Hertz (Hz)

The SI unit of frequency (ISO 80000-3 §3-13) equal to exactly one cycle per second (1 Hz = 1 s⁻¹). Named after German physicist Heinrich Rudolf Hertz, whose 1887-1888 experiments at Karlsruhe first demonstrated and measured electromagnetic waves and confirmed Maxwell's theory. Hz is the universal unit for periodic phenomena across physics, engineering, and consumer electronics: computer display refresh rates (60 Hz standard, 120/144/240 Hz gaming, 480 Hz high-end OLED esports monitors), residential and commercial AC mains power frequency per IEC 60038 (50 Hz universal except North America / Brazil / Liberia / Saudi Arabia at 60 Hz; aircraft 400 Hz per DO-160 to reduce transformer size and weight; ships often 400 Hz or 60 Hz), heart rate (resting ~1 Hz / 60 bpm), neuron firing rate (1-100 Hz peak), sound-wave pitch (human hearing 20 Hz - 20 kHz per ISO 226), seismic-wave frequencies (1-30 Hz for earthquake-engineering analysis per ASCE 7-22 site-response spectra), and rotating-machinery vibration analysis per ISO 10816. Hz is also the unit for radioactive-decay rate (the becquerel is 1 Bq = 1 disintegration/s = 1 Hz).

About Megahertz (MHz)

A frequency unit equal to exactly 1,000,000 Hz = 10⁶ Hz. MHz is the dominant band for commercial broadcasting, two-way-radio, and consumer wireless: FM (Frequency Modulation) commercial radio band 88-108 MHz per FCC Part 73; VHF television broadcast band 54-216 MHz (now repacked post-incentive auction); UHF TV 470-608 MHz; amateur (ham) radio 2 m band 144-148 MHz + 70 cm band 420-450 MHz per FCC Part 97; LMR (Land Mobile Radio) for public-safety + first-responders 150-174 MHz VHF and 450-470 MHz UHF per APCO P25 + DMR / NXDN / TETRA standards; cellular baseband frequencies in the original 800 MHz AMPS band and the later 900-960 MHz / 1700-2100 MHz LTE bands; older microprocessor clock speeds (Intel 8086 ~5 MHz; original Pentium 60-200 MHz; Pentium III 450 MHz - 1 GHz). Spectrum allocation by regulators (FCC, Ofcom, ETSI, ITU-R) is organized primarily in MHz bands in regulatory documents.

Understanding Hertz

The Hertz (symbol: Hz) is a unit of frequency. The SI unit of frequency (ISO 80000-3 §3-13) equal to exactly one cycle per second (1 Hz = 1 s⁻¹). Named after German physicist Heinrich Rudolf Hertz, whose 1887-1888 experiments at Karlsruhe first demonstrated and measured electromagnetic waves and confirmed Maxwell's theory.

Understanding Megahertz

The Megahertz (symbol: MHz) is a unit of frequency. A frequency unit equal to exactly 1,000,000 Hz = 10⁶ Hz. MHz is the dominant band for commercial broadcasting, two-way-radio, and consumer wireless: FM (Frequency Modulation) commercial radio band 88-108 MHz per FCC Part 73; VHF television broadcast band 54-216 MHz (now repacked post-incentive auction); UHF TV 470-608 MHz; amateur (ham) radio 2 m band 144-148 MHz + 70 cm band 420-450 MHz per FCC Part 97; LMR (Land Mobile Radio) for public-safety + first-responders 150-174 MHz VHF and 450-470 MHz UHF per APCO P25 + DMR / NXDN / TETRA standards; cellular baseband frequencies in the original 800 MHz AMPS band and the later 900-960 MHz / 1700-2100 MHz LTE bands; older microprocessor clock speeds (Intel 8086 ~5 MHz; original Pentium 60-200 MHz; Pentium III 450 MHz - 1 GHz).

Frequently Asked Questions

How do I convert Hertz to Megahertz?

The SI unit of frequency (ISO 80000-3 §3-13) equal to exactly one cycle per second (1 Hz = 1 s⁻¹). To convert Hertz to Megahertz, multiply by 1.0000e-6. For example, 25 Hz equals 0.000025 MHz.

How many Megahertz are in 1 Hertz?

There are 0.000001 Megahertz in 1 Hertz.

How many Hertz are in 1 Megahertz?

There are 1000000 Hertz in 1 Megahertz.

What is the formula for Hertz to Megahertz conversion?

The formula is: multiply by 1.0000e-6. This means 1 Hz = 0.000001 MHz.

Is a Hertz bigger than a Megahertz?

Yes. One Hertz is larger than one Megahertz because 1 Hz equals 0.000001 MHz, which is less than 1.

When do you need to convert between Hertz and Megahertz?

A frequency unit equal to exactly 1,000,000 Hz = 10⁶ Hz. Hertz and Megahertz are both frequency units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
