terabyte to gigabyte calculator

In today’s digital world, data is stored, shared, and processed in massive quantities. Whether you are dealing with computer storage, server management, cloud storage, or database systems, understanding data size conversions is essential. One of the most common conversions in the data storage world is from terabytes (TB) to gigabytes (GB).

Terabyte to Gigabyte Calculator

What is a Terabyte (TB)?

A terabyte is a unit of digital storage that equals 1,000 gigabytes (GB) in the decimal system. However, in the binary system commonly used in computing, 1 terabyte = 1,024 gigabytes.

  • 1 TB (decimal) = 1,000 GB
  • 1 TB (binary) = 1,024 GB

In practical use, storage manufacturers often use the decimal system, while computer systems typically use the binary system. This can sometimes cause confusion when checking actual available storage space.

What is a Gigabyte (GB)?

A gigabyte is a smaller unit of digital storage that equals 1,000 megabytes (MB) in the decimal system or 1,024 megabytes in the binary system.

  • 1 GB (decimal) = 1,000 MB
  • 1 GB (binary) = 1,024 MB

Gigabytes are commonly used to measure file sizes, software packages, and smaller storage devices like USB drives and memory cards.

Formula for Terabyte to Gigabyte Conversion

The formula for converting terabytes (TB) to gigabytes (GB) is straightforward:

Gigabytes (GB) = Terabytes (TB) × 1,000 (decimal system)
Gigabytes (GB) = Terabytes (TB) × 1,024 (binary system)

Which formula you use depends on whether you are using the decimal (SI units) or binary (computer science) measurement system.

This calculator ensures fast and precise results, making it ideal for professionals, students, and everyday users.

Examples of Terabyte to Gigabyte Conversion

Let’s go through a few examples to understand how the conversion works:

  1. Example 1: Convert 2 TB to GB
    • 2 × 1,000 = 2,000 GB (decimal)
    • 2 × 1,024 = 2,048 GB (binary)
  2. Example 2: Convert 5 TB to GB
    • 5 × 1,000 = 5,000 GB (decimal)
    • 5 × 1,024 = 5,120 GB (binary)
  3. Example 3: Convert 10 TB to GB
    • 10 × 1,000 = 10,000 GB (decimal)
    • 10 × 1,024 = 10,240 GB (binary)

These examples show how the results can slightly differ depending on whether you use the decimal or binary system.
