How to Convert Bytes to Gigabits

To convert bytes to gigabits, multiply the data size by the following conversion ratio: 8e-9 gigabits/byte.

Since one byte is equal to 8e-9 gigabits, you can use this simple formula to convert:

gigabits = bytes × 8e-9

The data size in gigabits is equal to the data size in bytes multiplied by 8e-9.

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

gigabits = (5 B × 8e-9) = 0.00000004 Gb

How Many Gigabits Are in a Byte?

There are 8e-9 gigabits in a byte, which is why we use this value in the formula above.

1 B = 8e-9 Gb|1 Gb = 125,000,000 B

Our byte to gigabit calculator automatically converts your data size measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Bytes and gigabits are both units used to measure data size. Keep reading to learn more about each unit.

What Is a Byte?

8 binary bits. It serves as a primary reference unit for measuring data size across scientific and practical applications. [1]

The byte is classified as an IEC binary unit of data size. Bytes can be abbreviated as B; for example, 1 byte can be written as 1 B.

As the primary coherent reference unit for data size in this category, all other data size units are mathematically anchored to the byte (B).

In practice, bytes (B) are widely used across standard data size applications within IEC binary workflows, engineering documentation, and technical data sheets.

What Is a Gigabit?

A gigabit is a unit of data size equal to 125,000,000 bytes (B), the base unit for data size. Equal to 1,000,000,000 bits (125 MB). [2]

The gigabit is classified as a metric and SI-compatible unit of data size. Gigabits can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.

In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigabit (Gb) a convenient decimal multiple of the byte (B).

In practice, gigabits (Gb) are widely used across large-scale industrial, bulk, and macro-level data size specifications within SI metric workflows, engineering documentation, and technical data sheets.

When converting data size between bytes (B) and gigabits (Gb), keep full floating-point precision (1 B = 8e-9 Gb; 1 Gb = 125,000,000 B) during intermediate calculations and round only the final gigabit figure to match your instrument tolerance.
