About gigahertz to megahertz conversion

Processor clock speeds and Wi-Fi bands are quoted in GHz, while radio and older hardware specifications use MHz. A gigahertz is exactly 1,000 megahertz, so the conversion shifts the decimal point three places.

1 GHz = 1,000 MHz
1 MHz = 0.001 GHz
MHz = GHz × 1000

How to use this converter

  1. 1

    Enter a value

    Type a number into the From box. It starts at 1 so you can see the basic ratio straight away. Thousands separators such as 1,250.5 are accepted.

  2. 2

    Choose your units

    This page opens with its own units selected. Use either dropdown to pick any other unit in the category, or tap a unit in the all-units list to make it the target.

  3. 3

    Read the result

    The answer updates as you type and the matching formula is shown underneath. There is no Convert button to press.

  4. 4

    Swap, copy or clear

    Swap reverses the direction, Copy Result copies a line such as 1 km = 0.621371 mi, and Clear empties the input so you can start again.

Supported formats

Input

  • Supported
    Whole numbers25
  • Supported
    Decimal numbers2.75

    Use a dot as the decimal separator.

  • Supported
    Negative numbers-40

    Calculated for every unit. Quantities such as length or weight are normally positive, while temperatures can be negative.

  • Supported
    Thousands separators1,250.5

    Commas must group digits in threes. 1,234 is read as one thousand two hundred thirty-four.

  • Supported
    Scientific notation1.5e6

    Useful for very large or very small values (1.5e6 = 1,500,000).

  • Not supported
    Comma as decimal mark2,5

    Type 2.5 instead.

  • Not supported
    Fractions1/2

    Type 0.5 instead.

  • Not supported
    Numbers with unit text5 km

    Enter only the number and choose the unit from the dropdown.

Output

Results use US English formatting (1,234.56) and show up to 6 decimal places with trailing zeros removed. Very small results appear in scientific notation, such as 9.0949e-13, instead of rounding to zero.

Worked examples

2.4 GHz Wi-Fi band

2.4 GHz2,400 MHz
2.4 × 1000 = 2,400

5 GHz Wi-Fi band

5 GHz5,000 MHz
5 × 1000 = 5,000

Processor clock speed

3.6 GHz3,600 MHz
3.6 × 1000 = 3,600

Good to know and limitations

Tips

  • FM radio runs from about 87.5 to 108 MHz, which is 0.0875 to 0.108 GHz.
  • Clock speed alone does not decide performance: a 4 GHz processor is not automatically faster than a 3.5 GHz one.
  • Frequency means cycles per second. Angular frequency (rad/s), RPM and BPM are not supported.
  • Converting frequency to wavelength is not supported.
  • Results show up to 6 decimal places. Values are not rounded during calculation, and a non-zero result that would display as 0 is shown in scientific notation.

Frequently asked questions

What is 1 GHz in MHz?

1 Gigahertz (GHz) equals 1,000 Megahertz (MHz).

How do I convert Gigahertz to Megahertz by hand?

Use MHz = GHz × 1000. For example, 2.4 GHz = 2,400 MHz.

What is 1 MHz in GHz?

1 Megahertz (MHz) equals 0.001 Gigahertz (GHz). Use the swap button to convert in this direction.
