Convert Petabyte to Megabit per Second (PB → Mbps)

Converting petabytes to megabits per second is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in petabytes

   Start with the number of petabytes (PB) you want to convert.
2. 2
   Multiply by 8,000,000,000

   The conversion factor from PB to Mbps is 8,000,000,000. Multiply your value by this number.
3. 3
   Read the result in megabits per second

   The result is your value in megabits per second (Mbps).

Multiply the value in petabytes by 8,000,000,000. For the reverse direction, multiply by 1.25 × 10^-10.

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

• ✗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.

What is the Petabyte?

The petabyte (PB) equals 1,000 terabytes (10¹⁵ bytes decimal) and rates large data centers, scientific research archives, and major social-media storage systems worldwide. The Large Hadron Collider generates about 30 petabytes of data per year, the U.S. Library of Congress digital collection is in the petabytes range, and major cloud-storage providers manage exabytes (1,000 PB) of data across their fleets. A petabyte could store roughly 250 million MP3 songs or about 13.3 years of HD video. The petabyte relates to the terabyte (1,000 TB = 1 PB), the exabyte (1,000 PB = 1 EB), and the gigabyte (10⁶ GB = 1 PB). Modern hyperscale data centers (Google, Amazon AWS, Microsoft Azure, Meta) store hundreds of petabytes per facility. The next consumer milestone — the petabyte hard drive — is expected within the next decade.

• Media archives and streaming libraries

What is the Megabit per Second?

Megabits per second (Mbps) is the standard unit for internet speeds, network bandwidth, and ISP connection ratings. Note: Mbps is megabits, not megabytes — the ratio is 8 bits per byte, so 100 Mbps = 12.5 MB/s download speed. Modern broadband home connections typically offer 100–1,000 Mbps download speeds, fiber-optic connections reach 1,000–10,000 Mbps (1–10 Gbps), and mobile 5G networks deliver 100–1,000+ Mbps. Internet streaming services recommend minimum speeds: HD video needs about 5 Mbps, 4K video needs 25 Mbps, and competitive online gaming benefits from 30+ Mbps with low latency. The Mbps relates to the megabyte per second (1 Mbps = 0.125 MB/s), the gigabit per second (1 Gbps = 1,000 Mbps), and the kilobit per second (1 Mbps = 1,000 kbps). The ITU and IEEE standardize network protocols using Mbps and multiples.
