One exabyte is exactly 1.000000000e+18 bytes, so converting exabytes to bytes is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
Eight bits; the addressable unit of computer memory. One billion gigabytes — the scale global internet traffic is counted in.
Decimal versus binary prefixes. Drive makers count a terabyte as 10¹² bytes; operating systems display 2⁴⁰ bytes and label it "TB". That is why a 1 TB disk shows as 931 GB. Bits versus bytes is a separate factor of eight on top. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into bytes, which is usually more useful than the bare number.
The formula
exabytes- The amount you are converting, in exabytes
1.00000000000e+18- The exact number of bytes in one exabyte
bytes- The converted result
How it works, step by step
- Enter the value in exabytes.
- It is multiplied by 1.00000000000e+18, the exact factor between the two units.
- The answer is shown in bytes, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A round figure: 1 EB in bytes
Take a round figure, roughly 1 EB. The conversion is a single multiplication — 1 × 1.00000e+18 — giving 1.00000e+18 B. Because the relationship is proportional, doubling the input doubles the answer to 2.00000e+18 B.
A larger figure: 100 EB in bytes
At 100 EB (a larger figure), the same quantity in bytes is 100 × 1.00000e+18 = 1.00000e+20 B. One exabyte is 1.00000e+18 bytes, so the numbers grow as expected.

Frequently asked questions
How many bytes are in one exabyte?
Exactly 1.00000000000e+18. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert exabytes to bytes?
bytes = exabytes × 1.00000000000e+18. Reversed, exabytes = bytes ÷ 1.00000000000e+18, which is the same as multiplying by 1.00000000000e-18.
Which is the bigger unit, the exabyte or the byte?
The exabyte. One exabyte equals 1.00000e+18 bytes.
What does this quantity actually measure?
Both units measure digital storage. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a exabyte?
One billion gigabytes — the scale global internet traffic is counted in.
What is a byte?
Eight bits; the addressable unit of computer memory.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
