About Kilobyte and Megabyte
The kilobyte is an SI decimal data unit equal to exactly 1,000 bytes. Small documents, icons, and emails are commonly measured in kilobytes. 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. One Kilobyte equals 0.001 Megabytes (1 KB = 0.001 MB). Kilobyte is used in text documents and emails and in icons and small images. Megabyte is used in photo and music file sizes.
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).
