MB to GB Converter

Convert megabytes (MB) to gigabytes (GB), with mebibytes (MiB) to gibibytes (GiB) and other storage units shown alongside.

What this tool does

Convert megabytes (MB) to gigabytes (GB), with mebibytes (MiB) to gibibytes (GiB) and other storage units shown alongside. Type an amount in megabytes, choose the units, and the tool converts it to gigabytes. It offers 7 data storage units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: Megabyte, Gigabyte, Terabyte, Kilobyte, Byte, Mebibyte, Gibibyte. Starts as Megabyte.
  • To: Choose one of the same 7 units as "From". Starts as Gigabyte.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from megabytes to gigabytes:

  • 1 MB = 0.001 GB
  • 5 MB = 0.005 GB
  • 10 MB = 0.01 GB
  • 50 MB = 0.05 GB
  • 100 MB = 0.1 GB

Multiply the number of megabytes by 0.001 to get gigabytes. Both units are exact definitions, so 0.001 is the exact factor: 1 MB = 0.001 GB.
