Terabit (Tb)
A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections.

A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255).
View the byte data unit pageHow to Convert Terabits to Bytes
To convert terabits to bytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity.
Tb measures data in bits—commonly used for memory addressing and low-level data specifications.
B measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: Terabits to Kilobytes.
1 Tb = 125,000,000,000 B (using SI decimal standard) — which means there are 125,000,000,000bytes in every terabit.
Tb to B conversion rate: 1 terabit equals 125,000,000,000bytes — the standard terabit to byte data storage conversion used by this calculator.

FAQs: Terabit to Byte Conversion
5 questions Quick answers on converting terabits to bytes, using the same factors as the converter above.
-
How many bytes are in 1 terabit?
1 Tb = 125,000,000,000 B
1 Terabit (Tb) equals 125,000,000,000 Bytes using the SI decimal standard.
-
How many terabits are in 1 byte?
1 Byte (B) equals 8.000000e-12 Terabits.
-
How do I convert terabits to bytes?
Tb × 125,000,000,000 = B
Multiply the terabit value by 125,000,000,000 to get bytes. For example, 10 Tb = 1,250,000,000,000 B. To convert back (vice versa), multiply bytes by 8.000000e-12.
-
Is a terabit bigger than a byte?
Tb is 125,000,000,000× larger than B
Yes. 1 Tb = 125,000,000,000 B, so the terabit is the larger data storage unit.
-
What is Terabit (Tb) commonly used for?
Common uses of the terabit (Tb) include: Data center interconnects, backbone networks, high-capacity optical links.
