How to Convert Terabits to Petabits
To convert terabits to petabits, divide by 1,000. This gives you the equivalent storage size in the target unit. Learn more: Pb to Terabits converter.
Tb: A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. Try the Terabits to PiB calculator.
Pb: A petabit is 1,000 terabits or 10^15 bits. Used for measuring massive network throughput. Check out our convert GB to Petabits.
1 Tb = 0.001 Pb (using SI decimal standard) — or equivalently, 1 Pb = 1,000Tb.
Tb to Pb Conversion Formula
// Convert Tb to Pb
Pb = Tb × 0.001
// Reverse: Convert Pb to Tb
Tb = Pb × 1,000
Tb to Pb Conversion Examples
100 Tb = 0.1 Pb
256 Tb = 0.256 Pb
500 Tb = 0.5 Pb
1,000 Tb = 1 Pb
2,048 Tb = 2.048 Pb
What Is a Terabit?
A terabit is 1,000 gigabits or 10^12 bits. Used for backbone network and data center connections. See also: Gibibits to b.
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. Use our how many KB/s in Megabits Per Second.
Common uses: Data center interconnects, backbone networks, high-capacity optical links Related: how many Bytes in a Tb.
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 Petabit?
A petabit is 1,000 terabits or 10^15 bits. Used for measuring massive network throughput. Check out our calculate KB to Pb.
The petabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. See also: GiB to Gib conversion rate.

💡 Storage Engineer Tip
For accurate capacity planning, always verify whether specifications use SI decimal (base 1000) or binary (base 1024) units. The difference becomes significant at larger scales.
