Why Convert Megahertz to Hertz?
About the Megahertz
Megahertz (MHz) is a unit of frequency measurement. 1 megahertz is equal to 1000000.0000000 hertz.
What is Hertz?
Hertz (Hz) is a unit of frequency measurement. 1 hertz is equal to 0.0000010 megahertz.
Frequency Conversion Applications
Frequency units span from hertz (cycles per second) through kilohertz (AM radio), megahertz (FM radio, processors), to gigahertz (Wi-Fi, 5G, microprocessors) and terahertz (scientific imaging). RPM to hertz conversion connects mechanical rotation to electrical frequency in generators and motors. Musicians convert between frequency (Hz) and musical pitch.

How to Convert MHZ to HZ (Megahertz to Hertz)?
We can convert megahertz to hertz by using an example.
Example:
Convert 20 Megahertz to Hertz?
We know 1 Megahertz = 1000000.0000000 hertz; 1 Hertz = 0.0000010 megahertz.
20 megahertz = ___Hz
20 × 1000000.0000000 = 20000000.00000 Hz (we know 1 megahertz = 1000000.0000000 hertz)
Answer:
20 megahertz = 20000000.00000 hertz
Megahertz to Hertz: Expanding MHz to Full Precision
Converting MHz to Hz by multiplying by 1,000,000 is essential when calculating exact timer periods, wavelengths, or programming hardware registers that require frequency in Hz. Processors, radio equipment, and test instruments often need the full Hz value for precise configuration.
- Identify the frequency in MHz.
- Multiply by 1,000,000.
- The result is the frequency in Hz.
- Example: 2.4 MHz × 1,000,000 = 2,400,000 Hz.
MHz to Hz Reference Table
Standard MHz frequencies expanded to their full Hz values:
| Megahertz | Hertz |
|---|---|
| 1 MHz | 1,000,000 Hz |
| 2.4 MHz | 2,400,000 Hz |
| 13.56 MHz | 13,560,000 Hz |
| 16 MHz | 16,000,000 Hz |
| 50 MHz | 50,000,000 Hz |
| 100 MHz | 100,000,000 Hz |

| 915 MHz | 915,000,000 Hz |
Detailed Examples: MHz to Hz
Question 1: A timer needs a 72 MHz clock. What is the frequency in Hz for register configuration?
Solution:
Hz = MHz × 1,000,000
= 72 × 1,000,000
= 72,000,000 Hz
Answer: 72 MHz = 72,000,000 Hz. If the timer needs a 1 ms period, divide: 72,000,000 ÷ 1,000 = 72,000 counts.
Question 2: Wi-Fi channel 1 center frequency is 2,412 MHz. Express in Hz.
Solution:
Hz = MHz × 1,000,000
= 2,412 × 1,000,000
= 2,412,000,000 Hz
Answer: 2,412 MHz = 2,412,000,000 Hz (2.412 GHz) — Wi-Fi 2.4 GHz band channel 1.
Question 3: A radar system operates at 5.8 MHz IF. What is this in Hz?
Solution:
Hz = MHz × 1,000,000
= 5.8 × 1,000,000
= 5,800,000 Hz
Answer: 5.8 MHz = 5,800,000 Hz intermediate frequency.

Timer Register Calculations: Why You Need Hz
When programming microcontroller timers, you work in Hz. For a 72 MHz STM32 needing a 50 Hz PWM: prescaler divides to a reasonable counter frequency, say 72,000,000 ÷ 72 = 1,000,000 Hz (1 MHz timer tick). Then auto-reload = 1,000,000 ÷ 50 = 20,000 counts for 50 Hz output. The full Hz value is essential for these integer arithmetic calculations in embedded firmware.
Wavelength Calculation from MHz
Radio wavelength (meters) = speed of light ÷ frequency (Hz). For 100 MHz: λ = 300,000,000 ÷ 100,000,000 = 3 meters. A quick shortcut: wavelength (m) = 300 ÷ frequency (MHz). So 433.92 MHz ≈ 300 ÷ 434 ≈ 0.69 m (69 cm). This is why 433 MHz antennas are about 17 cm (quarter-wave). Converting to Hz is needed for exact calculations.
Key Takeaways
- 1 MHz = 1,000,000 Hz (multiply by one million).
- Move the decimal six places right to convert MHz to Hz.
- Embedded systems and timer registers require frequency in Hz.
- Wavelength (m) = 300,000,000 ÷ frequency (Hz), or simply 300 ÷ MHz.
- The FM radio band is 87.5–108 MHz = 87,500,000–108,000,000 Hz.
Megahertz to Hertz Conversion Formula
hertz = megahertz × 1000000.0000000
1 megahertz = 1000000.0000000 hertz
1 hertz = 0.0000010 megahertz
Reverse: megahertz = hertz × 0.0000010
