⚡ GB → Bytes Converter
Gigabytes (GB)
1 GB =
1,000,000,000 bytes (decimal/SI)
1 GB =
1,073,741,824 bytes (binary/IEC)
💡 Note: Decimal: 1 GB = 1,000,000,000 bytes (storage vendors). Binary: 1 GiB = 1,073,741,824 bytes (OS file systems). This tool shows both standards.
📖 Understanding Gigabytes and Bytes
Gigabyte (GB): Decimal 1 GB = 1,000,000,000 bytes (10⁹). Binary 1 GiB = 1,073,741,824 bytes (2³⁰).
Byte (B): Fundamental unit of digital information, typically 8 bits.
Conversion formulas:
➜ Decimal: Bytes = GB × 1,000,000,000
➜ Binary: Bytes = GiB × 1,073,741,824
🔍 Real-world context
- 5 GB cloud storage = 5,000,000,000 bytes decimal / ~4.65 GiB binary.
- 128 GB SSD = 128,000,000,000 bytes decimal, but OS shows ~119 GiB.
- 1 GB RAM = 1,073,741,824 bytes (binary, since RAM uses binary addressing).
