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)

About Megahertz (MHz) and Hertz (Hz)

Understanding these frequency units used in electronics, telecommunications, and radio technology.

MHz vs Hz Comparison

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.

Magnitude Comparison

1 Hz 1 cycle/sec
1 MHz 1,000,000 cycles/sec
1 MHz = 10⁶ Hz

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:

  1. "Mega-" is a metric prefix meaning one million (10⁶)
  2. 1 megahertz = 1,000,000 hertz
  3. This follows the metric system's consistent scaling:
    • 1 kHz (kilohertz) = 1,000 Hz
    • 1 MHz (megahertz) = 1,000,000 Hz
    • 1 GHz (gigahertz) = 1,000,000,000 Hz
  4. Each step represents a 1,000x increase in frequency

Common Frequencies (MHz → Hz → Real-World Examples)

Megahertz (MHz) Hertz (Hz) Equivalent Application

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

Frequently Asked Questions

Common questions about megahertz to hertz conversions

Why is 1 MHz equal to 1,000,000 Hz?

The conversion factor comes from the metric system's prefixes:

  • "Mega-" (symbol: M) is a metric prefix meaning one million (10⁶)
  • Hertz (Hz) is the SI unit of frequency, defined as one cycle per second
  • Therefore, 1 megahertz (MHz) = 1,000,000 hertz (Hz)
  • This follows the consistent pattern of metric prefixes:
    • 1 kilohertz (kHz) = 1,000 Hz = 10³ Hz
    • 1 megahertz (MHz) = 1,000,000 Hz = 10⁶ Hz
    • 1 gigahertz (GHz) = 1,000,000,000 Hz = 10⁹ Hz
When would I need to convert between MHz and Hz?

Frequency conversions are essential in several technical fields:

  • Electronics engineering: Designing circuits, oscillators, and frequency-dependent components.
  • Communications: Working with radio, TV, Wi-Fi, and cellular frequencies that are often specified in MHz.
  • Computer technology: Describing processor clock speeds (often in GHz, which converts through MHz).
  • Science and research: Analyzing wave phenomena, spectroscopy, and various oscillatory systems.

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).

What's the difference between MHz, GHz, and kHz?

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:

  • Audio frequencies: Hz to kHz
  • AM/FM radio: kHz to MHz
  • Cellular networks and Wi-Fi: MHz to GHz
  • Computer processors: GHz
How accurate is this conversion for technical applications?

This conversion is mathematically exact and perfectly accurate for all technical applications because:

  • It's based on the definition of metric prefixes, which are internationally standardized
  • The relationship (1 MHz = 1,000,000 Hz) is a definition, not a measurement
  • Unlike some unit conversions that involve physical constants, this is a simple scaling factor
  • It's used in engineering, science, and technology worldwide without variation

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.
