Gigabits (Gb) to Bytes (B) calculator

Input the amount of gigabits you want to convert to bytes in the below input field, and then click in the "Convert" button. But if you want to convert from bytes to gigabits, please checkout this tool.


Formula used to convert Gb to B:

F(x) = x * 125000000

For example, if you want to convert 15 Gb to B, just replace x by 15 [Gb]:

15 Gb = 15*125000000 = 1875000000 B


  1. Multiply the amount of gigabits by 125000000.
  2. The result will be expressed in bytes.

About Gigabits (Gb)

A gigabit is a unit of measurement for digital information and computer storage. The prefix giga (which is expressed with the letter G) is defined in the International System of Units (SI) as a multiplier of 10^9 (1 billion). Therefore, 1 gigabit is equal to 1,000,000,000 bits and equal to 1,000 megabits. The symbol commonly used to represent a gigabit is Gb (sometimes as Gbit).

About Bytes (B)

A byte is a unit of digital information that represents eight (8) bits. It is widely used in computing and in digital communications. The symbol used to represent a byte is B (upper-case letter B). It was designated by the International Electrotechnical Commission (IEC) and Institute of Electrical and Electronics Engineers (IEEE).

The amount of bits that a byte represent changed over the years, but nowadays a byte represents 8 bits. With 1 byte you can represent numbers from 0 to 255.
