How to convert petabytes to bits
To convert a measurement in petabytes to bits, multiply the value by 8.000000e+15. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 PB to bits: 5 × 8.000000e+15 = 4.000000e+16 bit.
What is a petabyte?
A petabyte is 1,000,000,000,000,000 bytes (1,000 terabytes) under the SI decimal convention. The binary equivalent is the pebibyte (PiB). The petabyte is the scale of large enterprises and cloud providers. Notable milestones include estimates that major platforms ingest multiple petabytes of new data every day.
Common uses of petabytes include: Data-center and cloud-storage capacity; Big-data analytics and data lakes; Scientific datasets (genomics, astronomy); Large-scale media streaming archives.
What is a bit?
A bit is the smallest unit of digital information, representing a single binary value of 0 or 1. Eight bits make one byte. The term 'bit', a contraction of 'binary digit', was coined by statistician John Tukey and popularized by Claude Shannon in his 1948 paper founding information theory. It is the fundamental unit on which all digital data is built.
Common uses of bits include: Network and internet speeds (Mbps, Gbps); Data transfer and bandwidth measurement; Encryption key lengths (128-bit, 256-bit); Color depth and audio bit rates.

Here are some common values converted:
1 PB = 8.000000e+15 bit 5 PB = 4.000000e+16 bit 10 PB = 8.000000e+16 bit 50 PB = 4.000000e+17 bit 100 PB = 8.000000e+17 bit
Frequently asked questions
How many bits are in one petabyte?
One petabyte (PB) equals 8.000000e+15 bits (bit). Multiply any value in petabytes by 8.000000e+15 to convert to bits.
How do I convert petabytes to bits?
Multiply the value in petabytes by 8.000000e+15. For example, 5 PB × 8.000000e+15 = 4.000000e+16 bit.
How do I convert bits to petabytes?
Multiply the value in bits by 1.250000e-16, or divide by 8.000000e+15. Use the swap button on the converter above to reverse the direction.
Is the petabyte to bit conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for petabytes to bits?
The formula is: bit = PB × 8.000000e+15. This comes from the definition of both units relative to the byte.
