About Gibibyte and Mebibyte
The gibibyte is an IEC binary data unit equal to 1,024 mebibytes, or 1,073,741,824 bytes. It distinguishes binary capacity from a decimal gigabyte. The mebibyte is an IEC binary data unit equal to 1,024 kibibytes, or 1,048,576 bytes. It is commonly used for memory and binary file-size calculations. One Gibibyte equals 1024 Mebibytes (1 GiB = 1024 MiB). Gibibyte is used in computer memory capacity and in operating-system disk reports. Mebibyte is used in memory capacity calculations.
Precision and Rounding:This converter keeps SI decimal prefixes (1 KB = 1,000 bytes) separate from IEC binary prefixes (1 KiB = 1,024 bytes). Match the symbol used by your source before converting because some operating-system interfaces display binary quantities with decimal labels.
See our guide to megabits vs. megabytes if you're unsure which one your download speed is quoted in.
Data units follow NIST guidance: decimal SI prefixes use powers of 1,000, while IEC binary prefixes use powers of 1,024 (reference).
