How to Convert Terabytes to Gigabits
To convert terabytes to gigabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. You might also need: Gigabits to TB calculator.
TB is a byte-based unit used for measuring file sizes and storage capacity. Learn more: TB to Tebibytes converter.
Gb is a bit-based unit—multiply bytes by 8 to get bits. See also: Gibibytes to Gigabits conversion.
1 TB = 8,000 Gb (using SI decimal standard) — which means there are 8,000gigabits in every terabyte.
TB to Gb Conversion Formula
// Convert TB to Gb
Gb = TB × 8,000
// Reverse: Convert Gb to TB
TB = Gb × 0.000125

What Is a Terabyte?
A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Use our convert Terabits to Yobibits.
The terabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our Terabytes Per Second to Gibibytes Per Second calculator.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups Check out our Terabytes to Exbibits converter.
1 TB = 8 × 10¹² bits = 1 × 10¹² bytes.
The terabyte can be abbreviated as TB; for example, 1 terabyte can be written as 1 TB.
What Is a Gigabit?
A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. Try the Pebibits to Gigabits.
The gigabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Try the Kib → MiB.
