How to Convert Exabytes to Terabytes
To convert exabytes to terabytes, multiply by 1,000,000 (using SI decimal). Both units measure storage capacity—the difference is scale. Use our calculate TB to EB.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. Related: how many Petabits in a EB.
TB: A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Try the how many TB in Tebibits.
1 EB = 1,000,000 TB (using SI decimal standard) — which means there are 1,000,000terabytes in every exabyte.
EB to TB Conversion Formula
// Convert EB to TB
TB = EB × 1,000,000
// Reverse: Convert TB to EB
EB = TB × 0.000001
EB to TB Conversion Examples
100 EB = 100,000,000 TB
256 EB = 256,000,000 TB
500 EB = 500,000,000 TB
1,000 EB = 1,000,000,000 TB
2,048 EB = 2,048,000,000 TB
Binary Standard (Base 1024)
Using binary calculation: 1 EB = 1,048,576 TB
100 EB = 104,857,600 TB
1,000 EB = 1,048,576,000 TB
1,024 EB = 1,073,741,824 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. Learn more: Tebibits to Eb.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. See also: convert bps to Yottabytes Per Second.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation Use our Exabytes to Tb calculator.
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.
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. You might also need: Gb to Terabytes converter.

SI Decimal vs Binary: Why Two Different Standards?
When converting exabytes to terabytes, 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 |
Why Does My Hard Drive Show Less Space Than Advertised?
This difference in standards explains the common "missing hard drive space" confusion.
Example: A "500 GB" Hard Drive
- Contains exactly: 500,000,000,000 bytes
- macOS (SI Decimal): Displays 500 GB (divides by 1,000³)
- Windows (Binary): Displays 465 GB (divides by 1,024³)
The Verdict: Same bytes, same drive—just different math. No space is actually missing.
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.
💡 Storage Engineer Tip
Manufacturers label drives using SI decimal (base 1000). Windows divides by 1024 instead—that's why a "1 TB" drive shows as 931 GB. Same bytes, different math.
