Hertz to Megahertz: The Essentials
What is Hertz?
Hertz (Hz) is a unit of frequency measurement. 1 hertz is equal to 0.0000010 megahertz.
About the Megahertz
Megahertz (MHz) is a unit of frequency measurement. 1 megahertz is equal to 1000000.0000000 hertz.
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 HZ to MHZ (Hertz to Megahertz)?
We can convert hertz to megahertz by using an example.
Example:
Convert 20 Hertz to Megahertz?
We know 1 Hertz = 0.0000010 megahertz; 1 Megahertz = 1000000.0000000 hertz.
20 hertz = ___MHz
20 × 0.0000010 = 0.00002 MHz (we know 1 hertz = 0.0000010 megahertz)
Answer:
20 hertz = 0.00002 megahertz
Converting Hertz to Megahertz for Electronics and RF Design
Megahertz (MHz) is the standard unit for radio frequencies, CPU clocks in older systems, and crystal oscillators. Since 1 MHz = 1,000,000 Hz, converting Hz to MHz requires dividing by one million. This conversion bridges the gap between low-frequency specifications and the MHz notation used in datasheets and FCC filings.
- Start with the frequency in Hz.
- Divide by 1,000,000 (one million).
- The result is the frequency in MHz.
- Example: 27,000,000 Hz ÷ 1,000,000 = 27 MHz.
Hz to MHz Common Conversions
Frequencies from various domains expressed in both Hz and MHz:
| Hertz | Megahertz |
|---|---|
| 1,000,000 Hz | 1 MHz |
| 3,579,545 Hz | 3.58 MHz |
| 8,000,000 Hz | 8 MHz |
| 13,560,000 Hz | 13.56 MHz |
| 16,000,000 Hz | 16 MHz |
| 27,120,000 Hz | 27.12 MHz |
| 100,000,000 Hz | 100 MHz |
| 433,920,000 Hz | 433.92 MHz |
Solved Examples: Hz to MHz
Question 1: An NFC tag operates at 13,560,000 Hz. Express in MHz.
Solution:
MHz = Hz ÷ 1,000,000
= 13,560,000 ÷ 1,000,000
= 13.56 MHz
Answer: 13,560,000 Hz = 13.56 MHz — the global NFC/RFID standard frequency.
Question 2: A microcontroller crystal runs at 48,000,000 Hz. Convert to MHz.
Solution:
MHz = Hz ÷ 1,000,000
= 48,000,000 ÷ 1,000,000
= 48 MHz
Answer: 48,000,000 Hz = 48 MHz — common for ARM Cortex-M microcontrollers.
Question 3: A VHF marine radio channel is at 156,800,000 Hz. What is this in MHz?
Solution:
MHz = Hz ÷ 1,000,000
= 156,800,000 ÷ 1,000,000
= 156.8 MHz
Answer: 156,800,000 Hz = 156.8 MHz — VHF Channel 16, the international maritime distress frequency.

Why MHz Dominates in RF Engineering
Radio frequency engineers use MHz because most practical RF work falls in the 1–3,000 MHz range (1 MHz to 3 GHz). This encompasses AM/FM radio, TV broadcasting, cellular bands, Wi-Fi, Bluetooth, GPS, and most satellite communications. Writing these in Hz would require 6–9 digit numbers, while kHz would still need 3–6 digits. MHz keeps numbers in the manageable 1–3,000 range.
Crystal Oscillator Frequencies: Common MHz Values
Electronics designers choose specific crystal frequencies for practical reasons: 3.579545 MHz (NTSC color burst, widely available), 8 MHz and 16 MHz (convenient for microcontrollers), 11.0592 MHz (generates exact UART baud rates), 12 MHz (USB full-speed), 14.318 MHz (PC graphics), 25 MHz (Ethernet PHY), and 48 MHz (USB full-speed clock). Each serves a specific protocol requirement.
Key Takeaways
- 1 Hz = 0.000001 MHz (divide Hz by 1,000,000).
- Move the decimal six places left to convert Hz to MHz.
- MHz is the standard notation for radio frequencies and crystal oscillators.
- Common microcontroller clocks range from 8 MHz to 200+ MHz.
- The FM radio band spans approximately 87.5–108 MHz.
Hertz to Megahertz Conversion Formula
megahertz = hertz × 0.0000010
1 hertz = 0.0000010 megahertz
1 megahertz = 1000000.0000000 hertz
Reverse: hertz = megahertz × 1000000.0000000
