Hz to MHz Converter

Converting between hertz (Hz) and megahertz (MHz) is essential when working with frequencies in radio, Wi-Fi, computing, and telecommunications. One megahertz equals one million hertz, making MHz particularly useful when dealing with higher frequencies like FM radio broadcasts or processor clock speeds.

Hz to MHz Conversion Table

This table shows common frequency conversions from hertz to megahertz. These values appear frequently in radio broadcasting, computer specifications, and wireless communications.

Hertz (Hz)	Megahertz (MHz)	Common Use
50 Hz	0.00005 MHz	UK mains electricity frequency
1,000 Hz	0.001 MHz	Audio frequency range
10,000 Hz	0.01 MHz	High-pitched audio
100,000 Hz	0.1 MHz	Longwave radio
1,000,000 Hz	1 MHz	AM radio band
88,000,000 Hz	88 MHz	FM radio (lower end)
100,000,000 Hz	100 MHz	FM radio band
433,000,000 Hz	433 MHz	ISM band (remote controls)
868,000,000 Hz	868 MHz	European ISM band
2,400,000,000 Hz	2,400 MHz	Wi-Fi 2.4 GHz band

Conversion Formula

The relationship between hertz and megahertz is straightforward. Since “mega” means one million, the conversion simply involves dividing or multiplying by 1,000,000.

Hz to MHz Formula:

MHz = Hz ÷ 1,000,000

MHz to Hz Formula:

Hz = MHz × 1,000,000

Step-by-Step Conversion

Take your frequency value in hertz
Divide the value by 1,000,000 (or move the decimal point six places to the left)
The result is your frequency in megahertz

Example 1: Convert 50 Hz to MHz → 50 ÷ 1,000,000 = 0.00005 MHz

Example 2: Convert 88,000,000 Hz to MHz → 88,000,000 ÷ 1,000,000 = 88 MHz

Example 3: Convert 2,400,000,000 Hz to MHz → 2,400,000,000 ÷ 1,000,000 = 2,400 MHz (2.4 GHz)

Where You’ll Encounter These Frequencies

Understanding Hz and MHz matters in everyday life. Radio stations broadcast on specific megahertz frequencies. Your Wi-Fi router operates at 2.4 GHz (2,400 MHz) or 5 GHz. Older computer processors had clock speeds measured in megahertz before gigahertz became standard.

FM Radio Broadcasting

In the UK, FM radio stations broadcast between 87.5 MHz and 108 MHz. BBC Radio 1 transmits on 97.6–99.0 MHz depending on your location, whilst BBC Radio 4 uses 92.4–94.6 MHz. These frequencies fall perfectly within the VHF (Very High Frequency) band.

Wi-Fi Networks

Your home Wi-Fi uses either 2.4 GHz (2,400 MHz) or 5 GHz (5,000 MHz) bands. The 2.4 GHz band offers better range but slower speeds. The 5 GHz band provides faster data transfer but doesn’t penetrate walls as effectively.

Computer Processors

Early Pentium processors ran at 60–300 MHz in the 1990s. Modern processors operate in gigahertz, but many embedded systems and microcontrollers still use megahertz-range clock speeds. The Arduino Uno, for instance, runs at 16 MHz.

Frequency Measurement Units

Hertz forms the base unit for frequency measurement. Other units scale up or down using metric prefixes. Here’s how they relate to each other:

Hertz (Hz)Base unit – 1 Hz
Kilohertz (kHz)1 kHz = 1,000 Hz
Megahertz (MHz)1 MHz = 1,000,000 Hz
Gigahertz (GHz)1 GHz = 1,000,000,000 Hz
Terahertz (THz)1 THz = 1,000,000,000,000 Hz

Frequently Asked Questions

What does Hz measure?

Hz measures frequency, which counts how many cycles or oscillations occur per second. One hertz equals one cycle per second. This applies to sound waves, radio waves, electromagnetic radiation, and processor clock cycles.

Why use MHz instead of Hz?

MHz simplifies large numbers. Rather than saying a radio station broadcasts at 95,800,000 Hz, we say 95.8 MHz. It’s more practical for frequencies above one million hertz, which appear commonly in radio, television, and computing.

How many Hz equal 1 MHz?

One megahertz equals exactly 1,000,000 hertz. The prefix “mega” always means one million in the metric system. This conversion factor remains constant across all applications.

What’s the difference between MHz and Mbps?

MHz measures frequency (cycles per second), whilst Mbps measures data transfer speed (megabits per second). They’re completely different measurements. Your Wi-Fi might operate on a 2.4 GHz (2,400 MHz) frequency whilst delivering 100 Mbps data speeds.

Can you hear frequencies in MHz?

No, human hearing ranges from about 20 Hz to 20,000 Hz (20 kHz). Megahertz frequencies fall well beyond our hearing capability. However, radio receivers convert these MHz radio waves into audible sound waves.

Is higher MHz always better?

Not necessarily. In processors, higher clock speeds don’t always mean better performance—architecture matters too. In radio, different frequencies serve different purposes. Lower frequencies travel further, whilst higher frequencies carry more data.
