What Is a Yottabyte (YB)? Definition and Uses
A yottabyte is 1,000 zettabytes or 10^24 bytes. The largest SI unit for digital storage currently defined. Related: KB to Nibbles converter.
The yottabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our Yobibits Per Second to Ebps calculator.
Common uses: Theoretical storage discussions, future data projections, astronomical data You might also need: convert YB to Yobibits.
1 YB = 8 × 10²⁴ bits = 1 × 10²⁴ bytes.
The yottabyte can be abbreviated as YB; for example, 1 yottabyte can be written as 1 YB.
What Is a Zebibyte (ZiB)? Definition and Uses
A zebibyte is 1,024 exbibytes or 2^70 bytes. Theoretical unit for measuring massive binary data volumes. See also: Exbibits to ZiB.
The zebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Related: how many Tib in Zettabytes.
Common uses: Theoretical storage calculations, future capacity projections, global binary data Related: how many Pebibytes Per Second in a PB/s.
1 ZiB = 9 × 10²¹ bits = 1 × 10²¹ bytes.
The zebibyte can be abbreviated as ZiB; for example, 1 zebibyte can be written as 1 ZiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting yottabytes to zebibytes, 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.
