GB to TB Converter

Understanding Digital Storage Units

Digital storage is measured in bytes and its multiples. As we move up the scale, each unit represents approximately 1,000 times more storage than the previous unit. Understanding these units is crucial for managing data storage needs in today's digital world.

The Digital Storage Hierarchy

Unit	Symbol	Decimal Value (SI)	Binary Value
Byte	B	1 byte	8 bits
Kilobyte	KB	1,000 bytes	1,024 bytes
Megabyte	MB	1,000,000 bytes	1,048,576 bytes
Gigabyte	GB	1,000,000,000 bytes	1,073,741,824 bytes
Terabyte	TB	1,000,000,000,000 bytes	1,099,511,627,776 bytes

Decimal vs. Binary Measurements

There are two different systems used for measuring digital storage:

SI (Decimal) System

Based on powers of 10
1 KB = 1,000 bytes
1 GB = 1,000,000,000 bytes
1 TB = 1,000,000,000,000 bytes
Commonly used by storage manufacturers

Binary System

Based on powers of 2
1 KiB = 1,024 bytes
1 GiB = 1,073,741,824 bytes
1 TiB = 1,099,511,627,776 bytes
Used by operating systems and computer memory

Note:

This difference between decimal and binary measurements can lead to confusion. When you buy a 1 TB hard drive, the manufacturer uses the decimal definition (1,000,000,000,000 bytes), but your computer's operating system might display it as approximately 0.91 TB because it's using the binary definition.

Understanding Gigabytes (GB)

A gigabyte is one of the most commonly used units of digital storage:

In decimal terms: 1 GB = 1,000,000,000 bytes
In binary terms: 1 GB = 1,073,741,824 bytes
Common usages: Photos (~1-5 MB each), music files (~5-10 MB per song), movies (~700 MB-8 GB)
A single-layer DVD holds approximately 4.7 GB of data
Modern smartphones typically have between 64 GB to 512 GB of storage

Understanding Terabytes (TB)

A terabyte represents a significant amount of storage capacity:

In decimal terms: 1 TB = 1,000,000,000,000 bytes
In binary terms: 1 TB = 1,099,511,627,776 bytes
1 TB = 1,000 GB in decimal or 1,024 GB in binary
Common usages: External hard drives, desktop computers, servers
A 1 TB drive could hold approximately: 250,000 MP3 songs, 500 hours of HD video, or 1,000,000 photos
Modern enterprise hard drives typically range from 1 TB to 20 TB

Real-world Applications

How to Convert GB to TB

To convert gigabytes (GB) to terabytes (TB), follow these steps:

1
Take the number of gigabytes (GB)
2
Divide by 1024 (1 TB = 1024 GB)

Example:

1024 GB = 1024 / 1024 = 1 TB

2048 GB = 2048 / 1024 = 2 TB

512 GB = 512 / 1024 = 0.5 TB

Examples

Common Examples

Example 1 1 TB

1024 GB = 1 TB

Example 2 2 TB

2048 GB = 2 TB

Example 3 0.5 TB

512 GB = 0.5 TB

Example 4 1.5 TB

1536 GB = 1.5 TB
