Petabyte (PB) - Definition and Overview

What is Petabyte?

One Petabyte is equal to 10^15 or 1000^5 Bytes. Petabyte is a decimal unit defined as per SI standard. 1 Petabyte = 1000 Terabytes. The unit symbol for Petabyte is PB. Petabyte is not same as Pebibyte (PiB) that contains 1024^5 bytes. 1000 Petabytes = 1 Exabyte (EB).

Summary

  • A Petabyte (PB) is a unit of digital information storage used to denote the size of data
  • It is based on the decimal system, which is used in telecommunications and networking
  • One Petabyte is equal to 1,000,000,000,000,000 bytes, or 1000 Terabytes
  • This unit is part of the International System of Units (SI).

Byte (B) - Definition and Overview

What is Byte?

Byte is a unit of digital information that most commonly consists of eight bits. A single byte can be used to represent 256 different values. 1000 bytes = 1 Kilobyte (KB). 1024 bytes = 1 Kibibyte (KiB).

Summary

  • A byte is a unit of digital information that typically consists of eight bits
  • It is one of the most commonly used units in computing and can represent 256 different values (2^8)
  • Bytes are used to encode a wide variety of data, including characters in text, pixel values in images, and more
  • In terms of storage, 1000 bytes make up a kilobyte (KB) in the decimal system, while 1024 bytes make up a kibibyte (KiB) in the binary system.

How to Convert Petabyte to Byte?

1 Petabyte is equal to 1,000,000,000,000,000 Byte. To convert Petabyte to Byte, use this simple formula:

Byte = Petabyte x 1,000,000,000,000,000

So, just multiply the number of Petabyte by 1,000,000,000,000,000 to get equivalent value in Byte.

Example 1:

Convert 5 Petabyte to Byte
5 x 1,000,000,000,000,000 = NaN Byte

Example 2:

Convert 7.5 Petabyte to Byte
7.5 x 1,000,000,000,000,000 = NaN Byte
