How to Convert Gigabits to Petabytes
To convert gigabits to petabytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity. Learn more: Petabytes to Gb calculator.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications. See also: Gb to Kilobits converter.
PB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Try the Exabits to Petabytes conversion.
1 Gb = 0.000000125 PB (using SI decimal standard) — or equivalently, 1 PB = 8,000,000Gb.
Gb to PB Conversion Formula
// Convert Gb to PB
PB = Gb × 0.000000125
// Reverse: Convert PB to Gb
Gb = PB × 8,000,000

What Is a Gigabit?
A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. Check out our convert Gibibits to Exbibytes.
The gigabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our Mebibits Per Second to Bits Per Second calculator.
Common uses: Fiber internet speeds, enterprise networking, 10GbE connections You might also need: Gigabits to Tebibytes converter.
1 Gb = 1 × 10⁹ bits = 125 × 10⁶ bytes.
The gigabit can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.
What Is a Petabyte?
A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. Check out our Gibibytes to Petabytes.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: Yib → MiB.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives See also: convert Tibps to Tbps.
1 PB = 8 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The petabyte can be abbreviated as PB; for example, 1 petabyte can be written as 1 PB.

💡 Storage Engineer Tip
Remember: 8 bits = 1 byte. When your ISP advertises "100 Mbps," divide by 8 to get your actual download speed in MB/s (approximately 12.5 MB/s theoretical maximum).
