What is a Petabit and a Mebibit?

A petabit (Pb or Pbit) is a multiple of the bit unit for digital information or computer storage. The prefix peta- (symbol P) is defined in the International System of Units (SI) as a multiplier of 1015 (1 quadrillion, or 1 followed by 15 zeros). Therefore, 1 petabit = 1,000,000,000,000,000 bits. This is equivalent to 1,000 terabits (Tb) or 1,000,000 gigabits (Gb).

A mebibit (Mib) is a unit of digital information equal to 220 bits, which is exactly 1,048,576 bits. It uses the binary prefix 'mebi-' established by the International Electrotechnical Commission (IEC). The mebibit is closely related to the megabit (Mb), which is defined using the decimal prefix 'mega-' (106 or 1,000,000 bits).

Note: The Petabit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Mebibit belongs to the imperial/US customary system.

History of the Petabit and Mebibit

As data volumes and network speeds continued to increase dramatically beyond the terabit scale, the petabit became relevant for quantifying extremely large amounts of data and ultra-high transmission capacities. It strictly follows the SI definition of 'peta-' as 1015. The distinction between decimal (petabit, Pb) and binary (pebibit, Pib = 250 bits) became increasingly important at this scale, leading to the formalization of binary prefixes like 'pebi-' by the IEC to avoid ambiguity.

The prefix 'mebi-' (representing 220) was defined by the IEC in 1998 along with other binary prefixes (kibi-, gibi-, tebi-, etc.). This standardization aimed to eliminate the confusion caused by using SI prefixes (like kilo-, mega-, giga-) to denote both powers of 1000 (decimal) and powers of 1024 (binary) in computing contexts. The term 'mebibit' specifically refers to the 220 multiple of bits.

Common Uses for petabits and mebibits

Explore the typical applications for both Petabit (imperial/US) and Mebibit (imperial/US) to understand their common contexts.

Common Uses for petabits

Petabits are primarily used in contexts involving massive data scales:

Measuring the theoretical or actual data transfer rates of core internet backbones, major international communication links, and large-scale data center networks (often expressed in Pbps - petabits per second).
Quantifying the aggregate data traffic processed by major internet exchange points (IXPs) or national telecommunications networks over specific timeframes.
Describing the capacity of cutting-edge optical fiber communication systems and research networks.
Characterizing the sheer volume of data generated or processed in large scientific endeavors, such as high-energy physics experiments, climate modeling, or large astronomical surveys, especially when discussing data transmission or raw bit counts.
High-performance computing (HPC) environments dealing with massive datasets.

Common Uses for mebibits

While less common in everyday usage than the megabit (Mb) – often used for network speeds (Mbps) – the mebibit is important where binary precision for bit quantities is required:

Specifying memory chip capacities or data bus widths in technical documentation where sizes are based on powers of 2.
Internal calculations within data communication protocols, hardware design, or software that operate on binary multiples.
Theoretical calculations in computer science, information theory, and data transmission analysis.
Ensuring accuracy when comparing binary (Mib) and decimal (Mb) data quantities, especially in storage and memory contexts.

Frequently Asked Questions

Questions About Petabit (Pb)

How many bits are in a petabit?

There are exactly 1,000,000,000,000,000 bits (one quadrillion bits, or 1015 bits) in 1 petabit (Pb), according to the standard SI definition of the prefix 'peta-'.

What is the difference between a petabit (Pb) and a petabyte (PB)?

A petabit (Pb) measures data in bits and equals 1015 bits. It is commonly used for data transfer rates and network capacity.
A petabyte (PB) measures data in bytes. According to SI standards, it equals 1015 bytes. It is typically used for measuring large storage capacities. (Note: The term pebibyte (PiB) correctly refers to 250 bytes).

Since 1 byte = 8 bits, 1 petabyte (1015 bytes) is equal to 8 x 1015 bits, or 8 petabits. Therefore, a petabyte represents 8 times more data than a petabit.

What is the difference between a petabit (Pb) and a pebibit (Pib)?

A petabit (Pb) uses the decimal SI prefix 'peta-' and equals 1015 bits (1,000,000,000,000,000 bits).
A pebibit (Pib) uses the binary IEC prefix 'pebi-' and equals 250 bits (1,125,899,906,842,624 bits).

A pebibit is approximately 12.6% larger than a petabit (1 Pib ≈ 1.126 Pb). Use Pb for contexts adhering to decimal standards (like network speeds) and Pib when precise binary multiples (powers of 2) are required (often related to memory or specific storage architectures).

How many gigabits (Gb) are in a petabit (Pb)?

There are 1,000,000 gigabits (Gb) in 1 petabit (Pb). This is derived from the SI prefixes: 1 Pb = 1015 bits and 1 Gb = 109 bits. Therefore, 1 Pb / 1 Gb = 1015 / 109 = 106 = 1,000,000.

About Mebibit (Mib)

How many bits are in a mebibit?

There are exactly 220 bits in 1 mebibit (Mib). This equals 1,048,576 bits.

How many kibibits (Kib) are in a mebibit (Mib)?

There are 1,024 kibibits (Kib) in 1 mebibit (Mib). This is because 1 Mib = 220 bits and 1 Kib = 210 bits, and 220 / 210 = 210 = 1,024.

What is the difference between a mebibit (Mib) and a megabit (Mb)?

A mebibit (Mib) represents 220 bits (1,048,576 bits), using the binary prefix 'mebi-'. A megabit (Mb) represents 106 bits (1,000,000 bits), using the decimal prefix 'mega-'. A mebibit is approximately 4.86% larger than a megabit (1 Mib ≈ 1.0486 Mb).

What is the difference between a mebibit (Mib) and a mebibyte (MiB)?

A mebibit (Mib) measures information in bits, while a mebibyte (MiB) measures information in bytes. Assuming the standard 1 byte = 8 bits, 1 mebibyte (MiB) is equal to 8 mebibits (Mib). Both use the binary prefix 'mebi-' (220).
