How to convert bytes to gigabytes
Bytes and Gigabytes both measure data, so converting is a single multiplication. One B equals 1.0000e-9 GB, so you multiply your bytes value by 1.0000e-9.
Formula: gigabytes = bytes × 1.0000e-9. For example, 10 B = 1.0000e-8 GB.

Bytes and Gigabytes explained
Bytes (B): Eight bits, the basic unit for file sizes.
Gigabytes (GB): One billion bytes, used for videos, apps and storage.
When you'd convert bytes to gigabytes
You'll convert bytes to gigabytes whenever a measurement is given in one unit but you need it in the other — comparing bytes and gigabytes figures across regions, following a recipe or spec, or double-checking a number. Because 1 B is exactly 1.0000e-9 GB, the result is precise every time.
Frequently asked questions
How many gigabytes are in a byte?
One B equals 1.0000e-9 GB. Multiply your bytes figure by 1.0000e-9 to get gigabytes.
What is the formula to convert bytes to gigabytes?
gigabytes = bytes × 1.0000e-9. The factor 1.0000e-9 is exact.
What is 2 bytes in gigabytes?
2 B = 2.0000e-9 GB. You can enter any value in the converter above to get an instant result.
Is this Bytes to Gigabytes converter accurate?
Yes. It uses the standard conversion factor (1 B = 1.0000e-9 GB) defined by IEC 80000-13 — units of information (bit, byte), so results are exact to several decimal places.
