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

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

What is 5 gigabits per second in megabytes per second?

5 gigabits per second (5 Gbps) is equal to 625 megabytes per second (625 MB/s).

Which is larger, 1 gigabits per second (Gbps) or 1 megabytes per second (MB/s)?

One gigabits per second (Gbps) is larger than one megabytes per second (MB/s). Specifically, 1 Gbps contains 125 MB/s, whereas 1 MB/s is 0.008 Gbps.

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

To reverse the calculation from MB/s to Gbps, multiply your megabytes per second value by the inverse factor 0.008 (or divide by 125). 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 MB/s results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 Gbps ≈ 625.00 MB/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 Megabytes per Second

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

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

megabytes per second = gigabits per second × 125

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

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

megabytes per second = (5 Gbps × 125) = 625 MB/s

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

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

1 Gbps = 125 MB/s|1 MB/s = 0.008 Gbps

Our gigabits per second to megabytes 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 megabytes 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 Megabytes per Second?

A megabytes per second is a unit of data transfer rate equal to 8,000,000 bits per second (bps), the base unit for data transfer rate. Equal to 8 Megabits per second (8 Mbps). [2]

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

In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megabytes per second (MB/s) a convenient decimal multiple of the bits per second (bps).

In practice, megabytes per second (MB/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.
