How do you convert gigabytes per second to gigabits per second?

To convert gigabytes per second (GB/s) to gigabits per second (Gbps), multiply the data transfer rate in gigabytes per second by 8 (gigabits per second = gigabytes per second × 8).

What is 5 gigabytes per second in gigabits per second?

5 gigabytes per second (5 GB/s) is equal to 40 gigabits per second (40 Gbps).

Which is larger, 1 gigabytes per second (GB/s) or 1 gigabits per second (Gbps)?

One gigabytes per second (GB/s) is larger than one gigabits per second (Gbps). Specifically, 1 GB/s contains 8 Gbps, whereas 1 Gbps is 0.125 GB/s.

How do I convert back from gigabits per second (Gbps) to gigabytes per second (GB/s)?

To reverse the calculation from Gbps to GB/s, multiply your gigabits per second value by the inverse factor 0.125 (or divide by 8). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round GB/s to Gbps results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 GB/s ≈ 40.00 Gbps). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Gigabytes per Second to Gigabits per Second

To convert gigabytes per second to gigabits per second, multiply the data transfer rate by the following conversion ratio: 8 gigabits per second/gigabytes per second.

Since one gigabytes per second is equal to 8 gigabits per second, you can use this simple formula to convert:

gigabits per second = gigabytes per second × 8

The data transfer rate in gigabits per second is equal to the data transfer rate in gigabytes per second multiplied by 8.

For example, here's how to convert 5 gigabytes per second to gigabits per second using the formula above.

gigabits per second = (5 GB/s × 8) = 40 Gbps

How Many Gigabits per Second Are in a Gigabytes per Second?

There are 8 gigabits per second in a gigabytes per second, which is why we use this value in the formula above.

1 GB/s = 8 Gbps|1 Gbps = 0.125 GB/s

Our gigabytes per second to gigabits per second calculator automatically converts your data transfer rate measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Gigabytes per Second and gigabits per second are both units used to measure data transfer rate. Keep reading to learn more about each unit.

What Is a Gigabytes per Second?

A gigabytes per second is a unit of data transfer rate equal to 8,000,000,000 bits per second (bps), the base unit for data transfer rate. Equal to 8 Gigabits per second (8 Gbps). [1]

The gigabytes per second is classified as a metric and SI-compatible unit of data transfer rate. Gigabytes per Second can be abbreviated as GB/s; for example, 1 gigabytes per second can be written as 1 GB/s.

In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigabytes per second (GB/s) a convenient decimal multiple of the bits per second (bps).

In practice, gigabytes per second (GB/s) are widely used across large-scale industrial, bulk, and macro-level data transfer rate specifications within SI metric workflows, engineering documentation, and technical data sheets.

What Is a Gigabits per Second?

A gigabits per second is a unit of data transfer rate equal to 1,000,000,000 bits per second (bps), the base unit for data transfer rate. 1,000,000,000 bits per second. [2]

The gigabits per second is classified as a metric and SI-compatible unit of data transfer rate. Gigabits per Second can be abbreviated as Gbps; for example, 1 gigabits per second can be written as 1 Gbps.

In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigabits per second (Gbps) a convenient decimal multiple of the bits per second (bps).
