Terabytes (TB) to Bytes (B) Converter
The Terabytes (TB) to Bytes (B) Converter turns your Terabyte (TB) value into Bytes (B). Type your storage value in the input field — 1 TB = 1,000,000,000,000 B, calculated across both decimal (SI) and binary (IEC) standards.
Terabytes (TB) to Bytes (B) Converter
How to Convert Terabytes to Bytes
To convert terabytes to bytes, multiply by 1,000,000,000,000. This gives you the equivalent storage size in the target unit. You might also need: B to TB calculator.
TB: A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Try the TB to Pib converter.
B: A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). You might also need: Kb to B.
1 TB = 1,000,000,000,000 B (using SI decimal standard) — which means there are 1,000,000,000,000bytes in every terabyte.
TB to B Conversion Formula
// Convert TB to B
B = TB × 1,000,000,000,000
// Reverse: Convert B to TB
TB = B × 1.000000e-12Terabyte to Byte Conversion Examples
100 TB = 100,000,000,000,000 B
256 TB = 256,000,000,000,000 B
500 TB = 500,000,000,000,000 B
1,000 TB = 1.000000000000e+15 B
2,048 TB = 2.048000000000e+15 B
What Is a Terabyte (TB)? Definition and Uses
A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Learn more: Exabytes in Kibibits.
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 converting Terabits Per Second to Petabytes Per Second.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups Learn more: TB to Mib conversion rate.
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 Byte (B)? Definition and Uses
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). You might also need: calculate Tib to B.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our how many Zettabytes in a nibble.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) Check out our how many Gibps in Mebibytes Per Second.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.

SI Decimal vs Binary: Why Two Different Standards?
When converting terabytes to bytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
