About these units
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.
Petabyte (PB)
A petabyte is 1 quadrillion bytes in decimal (10¹⁵) or 1,125,899,906,842,624 bytes in binary (2⁵⁰). At this size, storage enters the realm of massive data infrastructures: internet archive collections, large-scale scientific simulations, genomic sequencing databases, machine learning datasets containing billions of records, multinational cloud storage networks. A single PB can store thousands of HD films, millions of e-books, or extensive enterprise backups. Petabytes mark the transition from everyday computing into large-scale data engineering, distributed systems, and global information ecosystems.
