Terabit [Tb] to Gigabit [Gb] Converter

Quick Reference

1 Terabit (Tb) = 1024 Gigabit (Gb)

1 Gigabit (Gb) = 0.0009765625 Terabit (Tb)

How to Convert Terabit to Gigabit

1 Tb = 1024 Gb
1 Gb = 0.0009765625 Tb

To convert Terabit to Gigabit, multiply the value by 1024. To convert Gigabit back to Terabit, divide by 1024.

Example: convert 10 Tb to Gb:
10 Tb = 10 x 1024 = 10240 Gb

↔ Convert Gigabit to Terabit

Terabit

Definition: A terabit (Tb) is a unit of data storage equal to 1,000,000,000,000 bits. It's a large multiple of the bit and is used for extremely high-capacity data measurement.

History/origin: The terabit uses the SI prefix 'tera' to denote one trillion. Its use became relevant with the ever-increasing demands for data storage and transfer in the digital age.

Current use: Terabits are primarily used to measure the capacity of network backbones, high-speed data links, and large-scale data storage systems. They are also used in describing the aggregate bandwidth of communication networks.

Gigabit

Definition: A gigabit (Gb) is a unit of data storage equal to 1,000,000,000 bits. It is a multiple of the bit and is commonly used to measure high-speed data transfer rates.

History/origin: Similar to the megabit, the gigabit uses the SI prefix 'giga' to denote one billion. Its usage grew with the increasing capacity and speed of digital communication technologies.

Current use: Gigabits are used to quantify very high data transfer rates, such as the speeds of Ethernet connections (e.g., Gigabit Ethernet) or fiber optic internet connections.
