About converting Petabytes to Bits
Petabytes (PB) and Bits (bit) are both units of digital storage, so converting between them is a single multiplication: multiply your Petabytes figure by 8,000,000,000,000,000. Ten Petabytes comes to 80,000,000,000,000,000 Bits, and a hundred works out at 800,000,000,000,000,000 Bits.
Rule of thumb: going from Petabytes to Bits multiplies, so the figure always grows — one Petabyte is already 8,000,000,000,000,000 Bits. If your answer came out smaller, you have the conversion the wrong way round.
What is a Petabyte?
A petabyte is a quadrillion bytes, a scale nothing a consumer owns comes close to. It belongs to data centres, archives and scientific instruments: particle physics at CERN, genome banks, and the disk arrays that streaming services and search engines run on. It is also the point at which moving data becomes a physical problem rather than a network one — the first image of a black hole was assembled from petabytes of telescope recordings that had to be flown between observatories on hard drives, because no internet connection could carry them in reasonable time.
What is a Bit?
A bit is a single binary digit — one yes or no, the smallest thing a computer can distinguish. The name is a contraction of "binary digit", credited to John Tukey and made famous by Claude Shannon’s 1948 paper founding information theory. The practical thing to know is that bits and bytes live in different places: connection and network speeds are quoted in bits per second, while file sizes are in bytes. That is why a 100 Mbps line downloads at about 12.5 MB/s and people assume they have been cheated. Nobody has — the two figures are counting different things.
To put both in perspective: a petabyte is data-centre scale, not anything you own, while a bit is a single yes-or-no.

Frequently asked questions
How many Bits are in one Petabyte?
There are 8,000,000,000,000,000 Bits in one Petabyte.
How do I convert Petabytes to Bits?
Multiply the number of Petabytes by 8,000,000,000,000,000. For example, 10 Petabytes = 80,000,000,000,000,000 Bits.
What is 100 Petabytes in Bits?
100 Petabytes is equal to 800,000,000,000,000,000 Bits.
How do I convert Bits to Petabytes?
Multiply the Bits value by 0 (or divide by 8,000,000,000,000,000).
Is this Petabytes to Bits conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Petabyte = 8,000,000,000,000,000 Bits is the complete value — nothing is rounded away.
