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

To convert gigabits per second (Gbps) to bytes per second (B/s), multiply the data transfer rate in gigabits per second by 125,000,000 (bytes per second = gigabits per second × 125,000,000).

What is 5 gigabits per second in bytes per second?

5 gigabits per second (5 Gbps) is equal to 625,000,000 bytes per second (625,000,000 B/s).

Which is larger, 1 gigabits per second (Gbps) or 1 bytes per second (B/s)?

One gigabits per second (Gbps) is larger than one bytes per second (B/s). Specifically, 1 Gbps contains 125,000,000 B/s, whereas 1 B/s is 8.000000e-9 Gbps.

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

To reverse the calculation from B/s to Gbps, multiply your bytes per second value by the inverse factor 8.000000e-9 (or divide by 125,000,000). You can also click the Swap button in the tool above to flip directions in one click.

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

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 Gbps ≈ 625,000,000.00 B/s). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Gigabits per Second to Bytes per Second

To convert gigabits per second to bytes per second, multiply the data transfer rate by the following conversion ratio: 125,000,000 bytes per second/gigabits per second.

Since one gigabits per second is equal to 125,000,000 bytes per second, you can use this simple formula to convert:

bytes per second = gigabits per second × 125,000,000

The data transfer rate in bytes per second is equal to the data transfer rate in gigabits per second multiplied by 125,000,000.

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

bytes per second = (5 Gbps × 125,000,000) = 625,000,000 B/s

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

There are 125,000,000 bytes per second in a gigabits per second, which is why we use this value in the formula above.

1 Gbps = 125,000,000 B/s|1 B/s = 8e-9 Gbps

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

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

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. [1]

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).

In practice, gigabits per second (Gbps) 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 Bytes per Second?

A bytes per second is a unit of data transfer rate equal to 8 bits per second (bps), the base unit for data transfer rate. Equal to 8 bits per second. [2]

The bytes per second is classified as an IEC binary unit of data transfer rate. Bytes per Second can be abbreviated as B/s; for example, 1 bytes per second can be written as 1 B/s.

When working with bytes per second (B/s) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, bytes per second (B/s) are widely used across standard data transfer rate applications within IEC binary workflows, engineering documentation, and technical data sheets.
