Convert bytes to gigabytes

Converting bytes to gigabytes is a common data task, whether you are checking a recipe, a spec sheet, a travel distance or a homework problem. Since 1 B equals 0.000000001 GB, the math is a single multiplication — and this page does it for you instantly, with the formula, a table of common values and answers to the questions people ask most.

How to convert bytes to gigabytes

To convert bytes to gigabytes, multiply the number of bytes by 0.000000001. For example, 10 B × 0.000000001 = 0.00000001 GB.

GB = B × 0.000000001

  1. Write down the value in bytes you want to convert.
  2. Multiply it by 0.000000001 (the exact B→GB factor).
  3. The result is your value in gigabytes. Check it below with the converter or the table.

About these units

Byte (B). A byte is 8 bits and holds a single text character. It is the base unit for measuring digital information, from file sizes to memory capacity.

Gigabyte (GB). A gigabyte is 1,000 megabytes, roughly an hour of HD video or 250 songs. Smartphone storage, RAM and data plans are specified in gigabytes.
