Megabyte Converters

Convert megabytes to kilobytes, gigabytes, terabytes, mebibytes and other digital storage units.

What this tool does

Convert megabytes to kilobytes, gigabytes, terabytes, mebibytes and other digital storage units. Type an amount in megabytes, choose the units, and the tool converts it to gigabytes. It offers 12 data storage units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 12 options, including Bit, Byte, Kilobyte, Megabyte, Gigabyte, Terabyte. Starts as Megabyte.
  • To: Choose one of the same 12 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.

Limitations

  • Decimal units (kilo, mega, giga) count in thousands, and binary units (kibi, mebi, gibi) count in 1024s. Operating systems and drive makers do not always use the same one, so check which your source means.
  • Converts the size of data only.
