Zettabytes (ZB) to Exabytes (EB) Converter
Convert zettabytes to exabytes.
1 ZB = 1,000 EB
How to convert ZB to EB
File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Zettabyte is 1021 bytes and 1 Exabyte is 1018 bytes. Divide one by the other and you get the ratio between the two units: 1021 ÷ 1018 = 103.
Zettabyte is the bigger unit, so you multiply. Every ZB holds 1,000 EB, which means the decimal point moves 3 places to the right.
These two sit side by side on the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB), so there is nothing to work out beyond remembering that every step is a factor of 1,000.
The formula
EB = ZB × 1,0001 ZB = 1,000 EB
Worked example 1: Converting 1 ZB
1 ZB × 1,000 = 1,000 EBThe decimal point moves 3 places to the right.
Analysts quote the total data created worldwide in a year in zettabytes.
Worked example 2: Converting 0.5 ZB
0.5 ZB × 1,000 = 500 EBThe decimal point moves 3 places to the right.
Worked example 3: Converting 12.75 ZB
12.75 ZB × 1,000 = 12,750 EBThe decimal point moves 3 places to the right.

Where ZB to EB comes up
A zettabyte is 1,000 exabytes, or a trillion gigabytes. Zettabytes appear in market reports and forecasts about how much data the world creates, copies and stores each year.
An exabyte is 1,000 petabytes, or a billion gigabytes. Exabytes describe traffic across whole networks, national-scale archives and industry forecasts, not any single file or drive.
Going from zettabytes down to exabytes always gives a bigger number, because the unit you land on is smaller. It is the usual direction when a limit or a form asks for a smaller unit than the one you have in mind.
ZB to EB FAQ
How many exabytes are in 1 zettabyte?
There are 1,000 exabytes in 1 zettabyte, so 1 ZB = 1,000 EB.
Is ZB to EB decimal or binary?
This page is decimal (SI), where 1 KB = 1,000 B. Operating systems often count in powers of 1,024 and still print KB, MB or GB, when they really mean KiB, MiB and GiB. At ZB the two systems differ by about 18.1%.
How do I convert EB to ZB?
Go the other way: divide by 1,000, which moves the decimal point 3 places to the left. The swap button on the converter does it for you.
