Formula

#
Core Formula
TB = PB x 1,000 (decimal) or TiB = PiB x 1,024 (binary)

How it works: In the decimal system, 1 PB = 1,000 TB = 1,000,000 GB. In binary, 1 PiB = 1,024 TiB = 1,048,576 GiB. The calculator converts your PB input to all smaller units using the selected system.

Worked Example

1 PB in decimal:
1Step 1: TB = 1 x 1,000 = 1,000 TB
2Step 2: GB = 1 x 1,000,000 = 1,000,000 GB
3Step 3: MB = 1 x 10^9 = 1,000,000,000 MB
4Step 4: Bytes = 1 x 10^15 = 1,000,000,000,000,000 bytes

Understanding Petabyte Storage

A petabyte is an enormous storage unit primarily used in enterprise and scientific contexts. Understanding PB conversions is important for data center planning, cloud storage budgeting, and big data analysis.

  • Decimal: 1 PB = 1,000 TB = 1,000,000 GB
  • Binary: 1 PiB = 1,024 TiB = 1,048,576 GiB
  • 1 PB can store roughly 250,000 HD movies or 13 years of continuous HD video
  • Major cloud providers manage storage in exabytes (1,000 PB)
  • The storage hierarchy goes: bytes, KB, MB, GB, TB, PB, EB, ZB, YB

Frequently Asked Questions

How many terabytes are in a petabyte?

In decimal: 1 PB = 1,000 TB. In binary: 1 PiB = 1,024 TiB. Cloud providers and data centers typically use the decimal standard when quoting petabyte-scale storage.

How many gigabytes are in a petabyte?

In decimal: 1 PB = 1,000,000 GB (one million gigabytes). In binary: 1 PiB = 1,048,576 GiB. To put that in perspective, 1 PB could hold about 250,000 HD movies or 500 billion pages of text.

What uses petabytes of storage?

Large organizations handle petabyte-scale data routinely. Netflix stores its entire video library in petabytes. Scientific research (genomics, particle physics) generates petabytes annually. Major cloud providers manage exabytes (1,000 PB) across their data centers.

What comes after petabyte?

The next unit is the exabyte (EB), where 1 EB = 1,000 PB. After that comes zettabyte (ZB) and yottabyte (YB). Global internet traffic reached several exabytes per month as of recent years.

How much does a petabyte of storage cost?

Cloud storage prices vary, but rough estimates place 1 PB of cloud storage at $20,000 to $25,000 per month depending on the provider and access tier. On-premises solutions using hard drives can be less expensive but require infrastructure and maintenance.

Is a petabyte the same as a pebibyte?

No. A petabyte (PB) uses the decimal standard: 10^15 bytes. A pebibyte (PiB) uses the binary standard: 2^50 bytes. A PiB is about 12.6% larger than a PB. The IEC introduced the "pebi" prefix to distinguish binary from decimal measurements.
