This page converts exabytes into bits using the factor 8.000000000e+18, and shows the reverse figure alongside it. Both units measure digital storage, which is why one number does the whole job.
A single binary digit — the smallest unit of information. 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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in bits, so you can sanity-check whether your answer is a plausible size.
The formula
exabytes- The amount you are converting, in exabytes
8.00000000000e+18- The exact number of bits in one exabyte
bits- The converted result
How it works, step by step
- Enter the value in exabytes.
- It is multiplied by 8.00000000000e+18, the exact factor between the two units.
- The answer is shown in bits, 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 bits
At 1 EB (a round figure), the same quantity in bits is 1 × 8.00000e+18 = 8.00000e+18 b. One exabyte is 8.00000e+18 bits, so the numbers grow as expected.
A larger figure: 100 EB in bits
At 100 EB (a larger figure), the same quantity in bits is 100 × 8.00000e+18 = 8.00000e+20 b. One exabyte is 8.00000e+18 bits, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many bits are in one exabyte?
Exactly 8.00000000000e+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 bits?
bits = exabytes × 8.00000000000e+18. Reversed, exabytes = bits ÷ 8.00000000000e+18, which is the same as multiplying by 1.25000000000e-19.
Which is the bigger unit, the exabyte or the bit?
The exabyte. One exabyte equals 8.00000e+18 bits.
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 bit?
A single binary digit — the smallest unit of information.
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.
