How to Convert Terabytes to Terabits
To convert terabytes to terabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. You might also need: convert Tb to TB.
TB is a byte-based unit used for measuring file sizes and storage capacity. Check out our TB to Gib calculator.
Tb is a bit-based unit—multiply bytes by 8 to get bits. Try the Yb to Tb converter.
1 TB = 8 Tb (using SI decimal standard) — which means there are 8terabits in every terabyte.
TB to Tb Conversion Formula
// Convert TB to Tb
Tb = TB × 8
// Reverse: Convert Tb to TB
TB = Tb × 0.125
TB to Tb Conversion Examples
100 TB = 800 Tb
256 TB = 2,048 Tb
500 TB = 4,000 Tb
1,000 TB = 8,000 Tb
2,048 TB = 16,384 Tb
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. See also: TiB to KB.
The terabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: Bytes Per Second in Zebibytes Per Second.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups Try the converting Terabytes to Nibbles.
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 Terabit?
A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. See also: b to Tb conversion rate.
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. Learn more: calculate B to KiB.

💡 Storage Engineer Tip
Multiply bytes by 8 to get bits. A 10 MB file requires 80 Mb of bandwidth—essential when calculating transfer times over network links.
