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

To convert megabits per second (Mbps) to gigabits per second (Gbps), multiply the data transfer rate in megabits per second by 0.001 (gigabits per second = megabits per second × 0.001).

What is 1000 megabits per second in gigabits per second?

1000 megabits per second (1000 Mbps) is equal to 1 gigabits per second (1 Gbps).

Which is larger, 1 megabits per second (Mbps) or 1 gigabits per second (Gbps)?

One gigabits per second (Gbps) is larger than one megabits per second (Mbps). Specifically, 1 Gbps equals 1,000 Mbps, while 1 Mbps is 0.001 Gbps.

How do I convert back from gigabits per second (Gbps) to megabits per second (Mbps)?

To reverse the calculation from Gbps to Mbps, multiply your gigabits per second value by the inverse factor 1,000 (or divide by 0.001). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round Mbps to Gbps results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 1000 Mbps ≈ 1.00 Gbps). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Megabits per Second to Gigabits per Second

To convert megabits per second to gigabits per second, multiply the data transfer rate by the following conversion ratio: 0.001 gigabits per second/megabits per second.

Since one megabits per second is equal to 0.001 gigabits per second, you can use this simple formula to convert:

gigabits per second = megabits per second × 0.001

The data transfer rate in gigabits per second is equal to the data transfer rate in megabits per second multiplied by 0.001.

For example, here's how to convert 1000 megabits per second to gigabits per second using the formula above.

gigabits per second = (1000 Mbps × 0.001) = 1 Gbps

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

There are 0.001 gigabits per second in a megabits per second, which is why we use this value in the formula above.

1 Mbps = 0.001 Gbps|1 Gbps = 1,000 Mbps

Our megabits 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.

Megabits 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 Megabits per Second?

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

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

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

In practice, megabits per second (Mbps) 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).

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.
