How to Convert Terabytes to Exabytes
To convert terabytes to exabytes, divide by 1,000,000 (using SI decimal). Both units measure storage capacity—the difference is scale. Related: EB → TB.
TB: A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Learn more: convert TB to TiB.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. You might also need: Yb to EB calculator.
1 TB = 0.000001 EB (using SI decimal standard) — or equivalently, 1 EB = 1,000,000TB.
TB to EB Conversion Formula
// Convert TB to EB
EB = TB × 0.000001
// Reverse: Convert EB to TB
TB = EB × 1,000,000
Terabyte to Exabyte Conversion Examples
100 TB = 0.0001 EB
256 TB = 0.000256 EB
500 TB = 0.0005 EB
1,000 TB = 0.001 EB
2,048 TB = 0.002048 EB
Binary Standard (Base 1024)
Using binary calculation: 1 TB = 0.000000953674316 EB
100 TB = 0.000095367431641 EB
1,000 TB = 0.000953674316 EB
1,024 TB = 0.0009765625 EB
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. Related: EiB to PB converter.
The terabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: Tbps to GB/s.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups You might also need: Terabytes in Yottabytes.
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 Exabyte?
An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. See also: converting Kibibytes to Exabytes.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: Yb to YB conversion rate.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation You might also need: calculate ZiB/s to Eibps.
1 EB = 8 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exabyte can be abbreviated as EB; for example, 1 exabyte can be written as 1 EB.

SI Decimal vs Binary: Why Two Different Standards?
When converting terabytes to exabytes, 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.
