- 1 GB = 1000000000 B
- 1 × 1000000000 = 1000000000 B
How to convert gigabytes to bytes
1 GB = 1,000,000,000 B, so multiply by 1,000,000,000 to go from gigabytes to bytes. Going the other way, 1 B = 1 × 10⁻⁹ GB.
B = GB × 1,000,000,000 GB = B × 1
Worked example:
1 GB = 1000000000 B 5 × 1000000000 = 5000000000 B
