What is a terabit per second?

A terabit per second (Tb/s) represents a data transfer rate of one trillion bits per second, used mainly to quantify high-speed network bandwidth.

How does gigabyte per second differ from gigabit per second?

Gigabyte per second (GB/s) measures data in bytes transferred per second, whereas gigabit per second (Gb/s) measures bits per second; 1 byte equals 8 bits.

Why is the conversion factor 128 between Tb/s and GB/s?

Because one terabit equals one trillion bits, and one gigabyte equals one billion bytes (8 bits per byte), the conversion factor is 128 to convert bits per second to bytes per second.

What Is This Tool?

This tool converts data transfer rates measured in terabits per second (Tb/s) to gigabytes per second (GB/s). It helps translate bit-based network speeds into byte-based throughput values commonly used for storage and memory performance evaluation.

How to Use This Tool?

Enter the data transfer rate in terabit per second (Tb/s).
Select terabit/second as the source unit and gigabyte/second as the target unit.
Click the convert button to see the equivalent gigabyte per second value.
Use the result to plan or compare network and data transfer speeds in bytes per second.

Key Features

Converts terabit/second values into gigabyte/second rates accurately based on SI unit definitions.
Includes common examples to illustrate the conversion process.
Supports understanding of data transfer rates in various telecommunications and computing contexts.
Browser-based and easy-to-use interface for quick conversions.

Examples

2 Tb/s converts to 256 GB/s using the formula 2 × 128 = 256.
0.5 Tb/s equals 64 GB/s calculated as 0.5 × 128 = 64.

Common Use Cases

Planning core internet backbone and long-haul optical fiber capacities.
Designing and optimizing hyperscale data-center interconnects with multi-Tb/s throughput.
Specifying carrier-grade optical transceivers and routers for telecommunications.
Expressing sequential storage device read/write speeds in gigabytes per second.
Converting network link speeds from bits per second to bytes per second for application-level throughput.
Sizing memory or bus bandwidth like DRAM or PCIe data paths.

Tips & Best Practices

Clarify whether gigabytes are measured using SI decimal units or binary-based units when comparing values.
Use this conversion for pure data rates and consider network protocol overhead separately.
Apply the conversion formula of 1 Tb/s = 128 GB/s consistently for accurate results.
Understand the context of your measurement to select correct units for precise data handling.

Limitations

Conversion assumes SI units where 1 GB = 10^9 bytes, not binary gigabytes (gibibytes).
Does not reflect network overhead, encoding schemes, or protocol inefficiencies which affect actual throughput.
Applicable only to raw data transfer rates without adjustments for communication layer details.
