Formula
bytes = gigabytes × 1073741824
Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.
About Gigabytes and Bytes
Gigabytes (GB): About one billion bytes; the dominant unit for consumer storage capacity. Common uses: RAM capacity, smartphone and SSD storage sizes, monthly cellular data plans, and movie file sizes.
Bytes (B): A unit of digital information, typically 8 bits; the size of a single ASCII character. Common uses: Memory addressing in low-level programming, file sizes for very small files, and the underlying base unit for all larger storage units.
How the conversion works
Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.
The exact relationship is bytes = gigabytes × 1073741824, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between gigabytes and bytes comes up wherever digital storage measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
