About Megabyte and Byte

The megabyte is an SI decimal data unit equal to exactly 1,000 kilobytes, or 1,000,000 bytes. Photos, songs, and app downloads are commonly measured in megabytes. The byte is 8 bits, the basic addressable unit of computer storage. One byte holds a single ASCII character, and all file sizes build up from it. One Megabyte equals 1000000 Bytes (1 MB = 1000000 B). Megabyte is used in photo and music file sizes and in app download sizes. Byte is used in file size fundamentals.

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).
