Units of Pebibyte

A pebibyte (PiB) is a unit of digital information storage that is based on binary prefixes, unlike the decimal-based petabyte (PB). The International Electrotechnical Commission (IEC) introduced this unit to standardize and avoid confusion between binary and decimal calculations.

• 1 Pebibyte (PiB) = 2^50 bytes
• 1 Pebibyte (PiB) = 1,024 Tebibytes (TiB)
• 1 Pebibyte (PiB) = 1,048,576 Gibibytes (GiB)
• 1 Pebibyte (PiB) = 1,125,899,906,842,624 bytes

Comparison with Petabyte

A petabyte (PB) uses decimal (base 10) calculations, while a pebibyte (PiB) uses binary (base 2) calculations. This distinction is crucial in computing where binary systems are the norm.

• 1 Petabyte (PB) = 1,000,000,000,000,000 bytes (10^15 bytes)
• 1 Pebibyte (PiB) = 1,125,899,906,842,624 bytes (2^50 bytes)
• 1 Petabyte (PB) = 0.888 Pebibytes (PiB)
• 1 Pebibyte (PiB) = 1.125 Petabytes (PB)
