About converting Petabytes to Megabytes
Petabytes (PB) and Megabytes (MB) are both units of digital storage, so converting between them is a single multiplication: multiply your Petabytes figure by 1,000,000,000. Ten Petabytes comes to 10,000,000,000 Megabytes, and a hundred works out at 100,000,000,000 Megabytes.
Rule of thumb: going from Petabytes to Megabytes multiplies, so the figure always grows — one Petabyte is already 1,000,000,000 Megabytes. 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 Megabyte?
A megabyte is a million bytes under the SI prefixes this site uses, though Windows will call 1,048,576 bytes a megabyte; the IEC name for that binary version is the mebibyte (MiB). The best illustration of how confused this all got is the 1.44 MB floppy disk, whose "MB" was neither one nor the other — it meant 1,024,000 bytes, a decimal thousand of binary kilobytes, and essentially nothing else has ever used that unit. Today the megabyte is the natural size of a photo, a song or a document.
To put both in perspective: a petabyte is data-centre scale, not anything you own, while a minute of MP3 audio is roughly a megabyte.

Frequently asked questions
How many Megabytes are in one Petabyte?
There are 1,000,000,000 Megabytes in one Petabyte.
How do I convert Petabytes to Megabytes?
Multiply the number of Petabytes by 1,000,000,000. For example, 10 Petabytes = 10,000,000,000 Megabytes.
What is 100 Petabytes in Megabytes?
100 Petabytes is equal to 100,000,000,000 Megabytes.
How do I convert Megabytes to Petabytes?
Multiply the Megabytes value by 0.000000001 (or divide by 1,000,000,000).
Is this Petabytes to Megabytes conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Petabyte = 1,000,000,000 Megabytes is the complete value — nothing is rounded away.
