Megahertz to Hertz Conversion:
1 Megahertz (MHz) = 1,000,000 Hertz (Hz)
Hz = MHz × 10⁶ | MHz = Hz ÷ 10⁶ (e.g., 2.5 MHz = 2,500,000 Hz; 5,000,000 Hz = 5 MHz)

Understanding these frequency units used in electronics, telecommunications, and radio technology.
| Unit | Definition | 1 Unit = | Common Uses |
|---|---|---|---|
| Hertz (Hz) | 1 cycle per second (SI unit of frequency) | 0.000001 MHz 10⁻³ kHz 10⁻⁶ MHz |
Audio frequencies, slow oscillations, basic frequency measurements |
| Megahertz (MHz) | 1,000,000 cycles per second | 1,000,000 Hz 1,000 kHz 10⁻³ GHz |
Radio frequencies, TV signals, processor clock speeds, Wi-Fi |
*Note: Both units measure frequency, representing the number of cycles per second of a periodic phenomenon.
1 megahertz represents one million cycles per second, making it 1,000,000 times larger than 1 hertz
The relationship between hertz and megahertz is based on metric prefixes:
| Megahertz (MHz) | Hertz (Hz) | Equivalent | Application |
|---|---|---|---|
| 0.001 MHz | 1,000 Hz | 1 kHz | Audio frequency (high pitch) |
| 1 MHz | 1,000,000 Hz | 10⁶ Hz | AM radio broadcasting |
| 2.4 MHz | 2,400,000 Hz | 2.4 × 10⁶ Hz | Shortwave radio |
| 50 MHz | 50,000,000 Hz | 5 × 10⁷ Hz | VHF television and radio |
| 2400 MHz | 2,400,000,000 Hz | 2.4 GHz | Wi-Fi, Bluetooth, microwave ovens |
| 3000 MHz | 3,000,000,000 Hz | 3 GHz | Computer processor |

Common questions about megahertz to hertz conversions
The conversion factor comes from the metric system's prefixes:
Frequency conversions are essential in several technical fields:
In these fields, different frequency ranges use appropriate units to avoid unwieldy numbers (e.g., 2.4 GHz instead of 2,400,000,000 Hz).
These are all units of frequency, differing only in magnitude:
1 kHz (kilohertz) = 1,000 Hz = 10³ Hz
1 MHz (megahertz) = 1,000,000 Hz = 10⁶ Hz = 1,000 kHz
1 GHz (gigahertz) = 1,000,000,000 Hz = 10⁹ Hz = 1,000 MHz
Each unit is 1,000 times larger than the previous one. This allows scientists and engineers to use units appropriate for the scale they're working with:
This conversion is mathematically exact and perfectly accurate for all technical applications because:
For precise technical work, ensure you're using the correct unit for your frequency range to avoid calculation errors, but the conversion factor itself is exact.
