How to Convert Terabits to Gigabits

To convert terabits to gigabits, multiply by 1,000. This gives you the equivalent storage size in the target unit. Check out our calculate Gb to Tb.

Tb: A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. You might also need: how many Zettabytes in a Tb.

Gb: A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. Use our how many Gb in Kilobits.

1 Tb = 1,000 Gb (using SI decimal standard) — which means there are 1,000gigabits in every terabit.

Tb to Gb Conversion Formula

// Convert Tb to Gb

Gb = Tb × 1,000

// Reverse: Convert Gb to Tb

Tb = Gb × 0.001

Terabit to Gigabit Conversion Examples

100 Tb = 100,000 Gb

256 Tb = 256,000 Gb

500 Tb = 500,000 Gb

1,000 Tb = 1,000,000 Gb

2,048 Tb = 2,048,000 Gb

What Is a Terabit?

A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. Related: Exabytes to Gib.

The terabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: convert Pbps to Gigabytes Per Second.

Common uses: Data center interconnects, backbone networks, high-capacity optical links See also: Terabits to Kib calculator.

1 Tb = 1 × 10¹² bits = 125 × 10⁹ bytes.

The terabit can be abbreviated as Tb; for example, 1 terabit can be written as 1 Tb.
