Gigabytes to bytes

1 gigabyte in bytes
1 GB = 1,000,000,000 B
B = GB × 1,000,000,000

To convert gigabytes to bytes, multiply by 1,000,000,000. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is B = GB × 1,000,000,000. Both units measure data, so the conversion is a fixed factor that never changes.

Common questions

How many bytes are in one gigabyte?
One gigabyte equals 1,000,000,000 bytes. B = GB × 1,000,000,000.
How do you convert gigabytes to bytes?
Use B = GB × 1,000,000,000. So 10 GB is 10,000,000,000 B.
How many gigabytes are in one byte?
One byte equals 1 × 10^-9 gigabytes, which is the reverse of the conversion above.
