1 Gigabyte (GB) is equal to 1,000,000,000 bytes in the decimal system, which is commonly used in storage device specifications.
In the binary system, which is often used in computing, 1 GB is equal to 1,073,741,824 bytes (calculated as 102 4 3 1024³).
The difference arises from the two measurement systems:
- Decimal (base 10): 1 GB = 10⁹bytes
- Binary (base 2): 1 GiB (Gibibyte) = 2³⁰ bytes
