How to convert megabytes to petabytes
To convert a measurement in megabytes to petabytes, multiply the value by 0.000000001. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 MB to petabytes: 5 × 0.000000001 = 0.000000005 PB.
What is a megabyte?
A megabyte is 1,000,000 bytes (1,000 kilobytes) under the SI decimal convention. The binary equivalent of 1,048,576 bytes is the mebibyte (MiB). As files grew beyond kilobytes, the megabyte became the everyday unit for documents, images, and songs. The decimal/binary ambiguity carried over from the kilobyte, which is why a '1 MB' file can be reported slightly differently by different systems.
Common uses of megabytes include: Photos, MP3 songs, and short documents; App download sizes; Mobile data allowances and usage; Digital camera image file sizes.
What is a petabyte?
A petabyte is 1,000,000,000,000,000 bytes (1,000 terabytes) under the SI decimal convention. The binary equivalent is the pebibyte (PiB). The petabyte is the scale of large enterprises and cloud providers. Notable milestones include estimates that major platforms ingest multiple petabytes of new data every day.
Common uses of petabytes include: Data-center and cloud-storage capacity; Big-data analytics and data lakes; Scientific datasets (genomics, astronomy); Large-scale media streaming archives.

Frequently asked questions
How many petabytes are in one megabyte?
One megabyte (MB) equals 0.000000001 petabytes (PB). Multiply any value in megabytes by 0.000000001 to convert to petabytes.
How do I convert megabytes to petabytes?
Multiply the value in megabytes by 0.000000001. For example, 5 MB × 0.000000001 = 0.000000005 PB.
How do I convert petabytes to megabytes?
Multiply the value in petabytes by 1,000,000,000, or divide by 0.000000001. Use the swap button on the converter above to reverse the direction.
Is the megabyte to petabyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for megabytes to petabytes?
The formula is: PB = MB × 0.000000001. This comes from the definition of both units relative to the byte.
