What comes after a terabyte? The next decimal data unit is a petabyte<\/strong>, followed by an exabyte<\/strong>, zettabyte<\/strong> and yottabyte<\/strong>. Beyond those are the newer SI prefixes ronna<\/strong> and quetta<\/strong>, which can form the names ronnabyte and quettabyte.<\/p>\n\n\n\n

These units describe extremely large quantities of digital information. A phone may be advertised in gigabytes, a personal drive in terabytes, and a large data system may be measured in petabytes or more. The names change, but the pattern is simple: in the decimal system, every step is 1,000 times larger than the one before it.<\/p>\n\n\n\n

Quick answer:<\/strong> GB \u2192 TB \u2192 PB \u2192 EB \u2192 ZB \u2192 YB \u2192 RB \u2192 QB. Each decimal step is 1,000 times larger.<\/p>\n<\/blockquote>\n\n\n\n

If you first need the everyday units, read KB vs MB vs GB: A Simple Guide to File Size<\/a>.<\/p>\n\n\n\n

This guide was checked against the BIPM and NIST prefix references on 28 August 2026. Standards and software displays can change, so use the unit definitions supplied by a device or service when an exact byte count matters.<\/p>\n\n\n\n

The International Bureau of Weights and Measures, usually called the BIPM, lists giga, tera, peta, exa, zetta, yotta, ronna and quetta as decimal SI prefixes. Ronna and quetta were added in 2022 to provide names for still larger quantities.<\/p>\n\n\n\n

What Is a Gigabyte?<\/h2>\n\n\n\n

A gigabyte is one billion bytes in decimal measurement:<\/p>\n\n\n\n

1 GB = 1,000,000,000 bytes<\/strong><\/p>\n\n\n\n

Gigabytes are common in everyday technology. They are used for phone storage, applications, games, videos, memory cards and monthly mobile-data allowances.<\/p>\n\n\n\n
