How to convert petabytes to gigabytes?

To convert petabytes (PB) to gigabytes (GB), start by picking the right data standard. Storage makers often use decimal (base-10), while many computer systems use binary (base-2).

Decimal conversion (base-10):
1 PB = 1,000,000 GB
GB = PB × 1,000,000
Binary conversion (base-2):
1 PB = 1,048,576 GB
GB = PB × 1,048,576

Example:

2 PB in decimal = 2 × 1,000,000 = 2,000,000 GB
2 PB in binary = 2 × 1,048,576 = 2,097,152 GB

Use decimal PB to GB for drive labels and marketing specs. Use binary PB to GB for many OS and memory-style counts.

Frequently asked questions

How many gigabytes are in a petabyte (PB to GB)?

In most storage and file-size use, 1 petabyte equals 1,000,000 gigabytes. This uses the decimal (base-10) system that many drive makers and cloud plans use.

How many gigabytes are in a pebibyte (PiB)?

A pebibyte is part of the binary (base-2) system. 1 PiB equals 1,048,576 gigabytes (since 1 PiB = 1,024 TiB and 1 TiB = 1,024 GB in this context).

What’s the difference between PB and PiB when converting to GB?

PB (petabyte) uses base-10 units, while PiB (pebibyte) uses base-2 units. The numbers look close, but the gap is large at this scale. PB to GB gives 1,000,000 GB, while PiB to GB gives 1,048,576 GB.

Which conversion should I use for petabytes to gigabytes?

Use PB to GB for drive labels, cloud storage, and most pricing. Use PiB to GB for system memory reports, some server tools, and other binary-based readouts. Match the unit shown in your data.

How do I convert petabytes to gigabytes by hand?

Multiply the number of petabytes by 1,000,000.

Example: 2.5 PB = 2.5 × 1,000,000 = 2,500,000 GB

How do I convert gigabytes to petabytes?

Divide gigabytes by 1,000,000.

Example: 750,000 GB = 750,000 ÷ 1,000,000 = 0.75 PB

Why do storage totals look “smaller” on my computer than the PB to GB math?

Many systems report storage using binary units (like GiB and TiB) even when they show “GB” or “TB.” That can make a decimal-labeled drive look smaller in the OS.

Are “GB” and “GiB” the same when converting from petabytes?

No. GB (gigabyte) is usually base-10. GiB (gibibyte) is base-2. If your tool shows GiB, the matching large unit is PiB, not PB.

How many gigabytes are in 0.1 petabyte?

Using decimal units, 0.1 PB = 100,000 GB. This comes from 0.1 × 1,000,000.

How many gigabytes are in 10 petabytes?

Using decimal units, 10 PB = 10,000,000 GB. This comes from 10 × 1,000,000.

Does the PB to GB conversion change for network data and bandwidth?

The unit math stays the same, but context changes. Network speeds often use bits (Gbps) while file sizes use bytes (GB). Don’t mix Gb (gigabits) with GB (gigabytes) without converting.

What’s a quick way to avoid unit mix-ups when converting PB to GB?

Check the letters and the base:

PB, GB usually mean decimal (base-10).
PiB, GiB mean binary (base-2).
b is bits, B is bytes.

How does this converter work?

The Calculate Box tool to convert petabytes to gigabytes uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a petabytes value in the box and have it instantly converted to gigabytes.
