Use the converter below to change any petabytes value into bits instantly — with formula, conversion table, and real-world examples.

8.0000e15

Conversion formula

Forward
bits = petabytes × 8.0000e15
Reverse
petabytes = bits × 1.2500e-16

Example: 10 PB × 8.0000e15 = 8.0000e16 b.

About both units

From

Petabyte

PB

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.

Bit

b

The bit is the smallest unit of digital information — a single 0 or 1. Coined by John Tukey in 1946. Network speeds, modem rates and compression ratios are measured in bits; file sizes and memory in bytes (8 bits each).

Real-world: Home fibre: 100 Mbps = 100,000,000 bps. AES key: 256 bits. MP3 bit rate: 128–320 kbps.

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 bits in a petabyte?
One petabyte equals 8.0000e15 bits.
How do I convert petabytes to bits?
Multiply the petabyte value by 8.0000e15 to get the equivalent in bits.
What is 100 petabytes in bits?
100 petabytes equals 8.0000e17 bits.
Is a petabyte bigger than a bit?
Yes. 1 petabyte equals 8.0000e15 bits, so one petabyte is larger.
How to convert petabytes to bits without a calculator?
Multiply by 8.0000e15 for a quick estimate; use a calculator for precise results.
