Exabytes (EB) to Bytes (B) Converter
Convert exabytes to bytes.
1 EB = 1,000,000,000,000,000,000 B
How to convert EB to Bytes (B)
File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Exabyte is 1018 bytes and 1 Byte is 100 bytes. Divide one by the other and you get the ratio between the two units: 1018 ÷ 100 = 1018.
Exabyte is the bigger unit, so you multiply. Every EB holds 1018 B, which means the decimal point moves 18 places to the right.
On the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB) these two are 6 steps apart. Every step is a factor of 1,000, so 6 steps means 1,000 multiplied by itself 6 times, which is 1018.
The formula
Bytes (B) = EB × 10181 EB = 1 × 1018 B1018 means 1 followed by 18 zeros
Worked example 1: Converting 1 EB
1 EB × 1018 = 1 × 1018 BThe decimal point moves 18 places to the right.
1 EB is only a small fraction of what worldwide internet traffic adds up to in one month.
Worked example 2: Converting 0.5 EB
0.5 EB × 1018 = 5 × 1017 BThe decimal point moves 18 places to the right.
Worked example 3: Converting 12.75 EB
12.75 EB × 1018 = 1.275 × 1019 BThe decimal point moves 18 places to the right.

Where EB to Bytes (B) comes up
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.
A byte is eight bits, enough to store one character of plain English text. Bytes show up whenever you need the exact number: file properties, HTTP headers, memory buffers, database column limits and the counts programs print in logs.
Bytes are the base unit, so this gives the exact count that programs, APIs and file properties report.
Going from exabytes down to bytes 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.
EB to Bytes (B) FAQ
How many bytes are in 1 exabyte?
There are 1018 bytes in 1 exabyte, so 1 EB = 1018 B.
Is EB to B 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 EB the two systems differ by about 15.3%.
How do I convert B to EB?
Go the other way: divide by 1018, which moves the decimal point 18 places to the left. The swap button on the converter does it for you.
