Conversion formula

Forward

megabytes = petabytes × 1,000,000,000

Reverse

petabytes = megabytes × 1.0000e-9

Example: 10 PB × 1,000,000,000 = 10,000,000,000 MB.

About both units

From

Petabyte

The petabyte equals 10¹⁵ bytes. Used for datacenter storage, scientific datasets and video archives. 1 PB could hold the text of 500 billion pages.

Real-world: Netflix total catalog: many PB. CERN LHC data: 100+ PB/year. YouTube uploads: EB scale now.

Megabyte

The megabyte equals 1,000,000 bytes (SI) or 1,048,576 bytes (binary, MiB). Used for photos, songs and medium-size documents. A standard MP3 song is 3–5 MB.

Real-world: MP3 song: 3–5 MB. High-res JPEG: 2–8 MB. PDF ebook: 5–50 MB.

Tips & common mistakes

Quick tips

1 PB = 1000 TB = 10¹⁵ B.
PiB uses binary multiples — rare in everyday context.
Scale beyond PB: EB (exabyte, 10¹⁸) and ZB (zettabyte, 10²¹).

Avoid these

Using PB when TB suffices — everyday use rarely needs PB.
Mixing PB and PiB — 12.6% difference.
Ignoring tape vs spinning-disk storage economics at PB scale.

Frequently asked questions

How many megabytes in a petabyte?

One petabyte equals 1,000,000,000 megabytes.

How do I convert petabytes to megabytes?

Multiply the petabyte value by 1,000,000,000 to get the equivalent in megabytes.

What is 100 petabytes in megabytes?
