Formula
megabytes = gigabytes × 1024
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 Megabytes
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.
Megabytes (MB): 1,048,576 bytes (binary, IEC) or 1,000,000 bytes (decimal, depending on context); 1 MB ≈ the size of a small image or short audio clip. Common uses: File sizes for images, documents, and short videos; RAM in older devices; download size budgets for web pages.
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 megabytes = gigabytes × 1024, 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 megabytes 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.
