How to Convert Gigabits to Terabytes
To convert gigabits to terabytes, multiply the data size by the following conversion ratio: 0.000125 terabytes/gigabit.
Since one gigabit is equal to 0.000125 terabytes, you can use this simple formula to convert:
The data size in terabytes is equal to the data size in gigabits multiplied by 0.000125.
For example, here's how to convert 5 gigabits to terabytes using the formula above.
How Many Terabytes Are in a Gigabit?
There are 0.000125 terabytes in a gigabit, which is why we use this value in the formula above.
Our gigabit to terabyte calculator automatically converts your data size measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Gigabits and terabytes are both units used to measure data size. Keep reading to learn more about each unit.
What Is a Gigabit?
A gigabit is a unit of data size equal to 125,000,000 bytes (B), the base unit for data size. Equal to 1,000,000,000 bits (125 MB). [1]
The gigabit is classified as a metric and SI-compatible unit of data size. Gigabits can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.
In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigabit (Gb) a convenient decimal multiple of the byte (B).
In practice, gigabits (Gb) are widely used across large-scale industrial, bulk, and macro-level data size specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Terabyte?
A terabyte is a unit of data size equal to 1e+12 bytes (B), the base unit for data size. SI decimal standard: 1,000,000,000,000 bytes (1,000 GB). [2]
The terabyte is classified as a metric and SI-compatible unit of data size. Terabytes can be abbreviated as TB; for example, 1 terabyte can be written as 1 TB.
In the metric system, "tera" is the standard SI prefix for trillions, or 10¹². This makes the terabyte (TB) a convenient decimal multiple of the byte (B).
In practice, terabytes (TB) are widely used across large-scale industrial, bulk, and macro-level data size specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting data size between gigabits (Gb) and terabytes (TB), keep full floating-point precision (1 Gb = 0.000125 TB; 1 TB = 8,000 Gb) during intermediate calculations and round only the final terabyte figure to match your instrument tolerance.
