How to Convert Terabits to Petabytes
To convert terabits 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: PB to Tb conversion rate.
Tb measures data in bits—commonly used for memory addressing and low-level data specifications. Related: converting Terabits to Kilobytes.
PB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Check out our Tebibits in Petabytes.
1 Tb = 0.000125 PB (using SI decimal standard) — or equivalently, 1 PB = 8,000Tb.
Tb to PB Conversion Formula
// Convert Tb to PB
PB = Tb × 0.000125
// Reverse: Convert PB to Tb
Tb = PB × 8,000
Tb to PB Conversion Examples
100 Tb = 0.0125 PB

What Is a Terabit?
A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. Check out our Kib to Pb.
The terabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our KB/s to KiB/s converter.
Common uses: Data center interconnects, backbone networks, high-capacity optical links Check out our Tb to Yb calculator.
1 Tb = 1 × 10¹² bits = 125 × 10⁹ bytes.
The terabit can be abbreviated as Tb; for example, 1 terabit can be written as 1 Tb.
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. Use our convert Yb to PB.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: Tib → EiB.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives You might also need: Mebibits Per Second to Megabits Per Second.
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).
