About Megabyte and Terabyte

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 terabyte is an SI decimal data unit equal to exactly 1,000 gigabytes, or one trillion bytes. Drives, backup systems, and media libraries are commonly terabyte-scale. One Megabyte equals 0.000001 Terabytes (1 MB = 0.000001 TB). Megabyte is used in photo and music file sizes and in app download sizes. Terabyte is used in hard drive and SSD capacity.

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).
