What does gigabyte per second (SI def.) mean?

It is a data transfer rate defined as one gigabyte equaling 10⁹ bytes transferred each second, following the SI prefix standard.

Why convert gigabyte/second to byte/second?

Converting to byte/second expresses data rates in a fundamental unit, allowing detailed analysis and compatibility with devices or reports.

Are there different definitions of a gigabyte?

Yes, the SI gigabyte equals 10⁹ bytes, while binary definitions like gibibyte use 2³⁰ bytes, so conversions depend on the definition used.

What Is This Tool?

This tool converts data transfer rates expressed in gigabytes per second (SI definition) into bytes per second [B/s]. It is designed for accurate transformation between these units used in computing, networking, and data storage environments.

How to Use This Tool?

Enter the value in gigabyte per second (SI def.) that you want to convert.
Select gigabyte per second (SI def.) as the source unit.
Choose byte per second [B/s] as the target unit.
Initiate the conversion to see the equivalent data rate in bytes per second.

Key Features

Converts data rates from gigabyte per second (SI) to byte per second.
Supports widely used SI prefix definitions for data throughput.
Browser-based and easy to use with clear input and output units.
Provides practical examples illustrating common conversion values.

Examples

2 gigabyte/second (SI def.) converts to 2 × 1,000,000,000 = 2,000,000,000 byte/second [B/s].
0.5 gigabyte/second (SI def.) converts to 0.5 × 1,000,000,000 = 500,000,000 byte/second [B/s].

Common Use Cases

Specifying network or data-center link throughput, such as backbone or aggregation interfaces.
Describing sequential read/write speeds of storage devices like SSDs and NVMe arrays.
Expressing interconnect or memory bandwidth in high-performance computing and server systems.
Reporting file transfer speeds during downloads, uploads, and backups.
Specifying data rates in embedded systems, telemetry, and instrumentation.

Tips & Best Practices

Use this conversion to translate large-scale data rates into fundamental units for detailed analysis.
Keep in mind that byte/second units may get very large for high rates and consider scaling to kB/s or MB/s for clarity.
Confirm whether bandwidth is reported in bits per second or bytes per second before converting for accurate comparisons.
Apply the conversion in contexts such as data centers, HPC, and communications to ensure consistency.

Limitations

This conversion uses the SI definition of gigabyte (1 GB = 10⁹ bytes), which differs from binary-based units like GiB.
Byte/second units may become very large and unwieldy for very high data rates without further scaling.
Bandwidth is sometimes given in bits per second, requiring additional conversion steps.

Key Terminology

Gigabyte per second (SI def.): A data transfer rate equal to 1 gigabyte (10^9 bytes) transferred every second, using the SI prefix standard.
Byte per second [B/s]: A unit measuring data transfer rate where one byte is transmitted or processed each second, often scaled using SI prefixes.
Data transfer rate: The amount of digital data moved from one place to another per unit of time, commonly expressed in bytes or bits per second.
