How to Convert Terabytes to Exbibytes
To convert terabytes (decimal/SI) to exbibytes (binary/IEC), multiply by 0.000000867361738. Decimal units use base 1,000, while binary units use base 1,024. See also: calculate EiB to TB.
TB is a decimal (SI) unit—what storage manufacturers advertise. 1 TB = 1,000 of the smaller unit. Try the how many Yobibits in a TB.
EiB is a binary (IEC) unit—what operating systems often display. 1 EiB = 1,024 of the smaller unit. Check out our how many EiB in Yobibits.
1 TB = 0.000000867361738 EiB (using SI decimal standard) — or equivalently, 1 EiB = 1,152,922TB.
TB to EiB Conversion Formula
// Convert TB to EiB
EiB = TB × 0.000000867361738
// Reverse: Convert EiB to TB
TB = EiB × 1,152,922

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. Learn more: Yobibytes to PiB.
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: convert Ybps to Terabytes Per Second.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups Try the Terabytes to GiB calculator.
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 Exbibyte?
An exbibyte is 1,024 pebibytes or 2^60 bytes. Used for hyperscale storage in binary measurements. Use our MiB to Exbibytes converter.
The exbibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Check out our Yobibits to Gigabits conversion.
Common uses: Hyperscale data centers, global storage statistics in binary, cloud provider capacity See also: convert Bits Per Second to Yottabytes Per Second.
1 EiB = 9 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exbibyte can be abbreviated as EiB; for example, 1 exbibyte can be written as 1 EiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting terabytes to exbibytes, 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
The ~9.95% difference between binary and decimal units compounds at each level. A 1 TB drive shows as 931 GiB in Windows because of this standard mismatch—no space is actually lost.
