About Gigabyte and Terabyte

Gigabytes (GB) and terabytes (TB) measure large storage capacities. One terabyte equals 1,000 gigabytes (decimal) or 1,024 gigabytes (binary). Terabyte-scale storage is now common for personal computers and cloud services.

Common Uses for This Conversion

Planning storage purchases, understanding server capacities, calculating backup needs, and comparing cloud storage options for large data sets.

💡Did You Know?

The Library of Congress contains about 17 TB of text data. A single human brain's memory capacity is estimated at 2.5 petabytes (2,500 TB)—far exceeding any computer storage currently available.

Frequently Asked Questions

KB (kilobyte) uses decimal prefixes: 1 KB = 1,000 bytes. KiB (kibibyte) uses binary prefixes: 1 KiB = 1,024 bytes. This distinction matters for accuracy—a 500 GB hard drive actually holds about 465 GiB. The IEC introduced binary prefixes (kibi, mebi, gibi) in 1998 to clarify this.
In decimal (SI) units: divide MB by 1,000 to get GB. In binary units: divide MiB by 1,024 to get GiB. For example, 2,000 MB = 2 GB, or 2,048 MiB = 2 GiB. Most storage manufacturers use decimal units, while operating systems often use binary.
A bit (binary digit) is the smallest unit of data, representing 0 or 1. A byte typically contains 8 bits and can represent values from 0-255. Internet speeds are usually measured in bits (Mbps), while file sizes use bytes (MB). To convert Mbps to MBps, divide by 8.
Drive manufacturers use decimal units (1 GB = 1,000,000,000 bytes), but operating systems often display binary units (1 GiB = 1,073,741,824 bytes). A 500 GB drive contains 500 billion bytes, but Windows shows it as ~465 GB because it uses binary calculation.
