About these units
Terabyte (10^12 bytes) (TB (10^12))
A decimal terabyte equals 1 trillion bytes, a unit that defines modern large-capacity storage devices—from consumer HDDs to enterprise backup systems. The distinction between binary (1.099 trillion bytes) and decimal terabytes becomes especially noticeable at this scale. Disk manufacturers universally use decimal TB, while many file systems report binary values unless specifically configured otherwise. Terabytes represent massive datasets, enabling high-resolution video libraries, large backups, and entire scientific databases.
Megabyte (10^6 bytes) (MB (10^6))
A decimal megabyte equals 1,000,000 bytes, used widely for describing hard disk storage, file sizes, and digital media capacity. Manufacturers favor decimal prefixes because they produce cleaner, larger-sounding numbers compared to binary equivalents. For example, a "500 MB" device would be smaller in binary units. Consumers and engineers must interpret megabytes within context, distinguishing whether a manufacturer intends binary or decimal. Although decimal megabytes dominate mass-storage descriptions, binary megabytes remain common in system memory and software.
