Gigabits Conversion (Gbit)

Gigabit is the unit of digital information with prefix giga (109).
1 gigabit is equal to 109 bits = 1,000,000,000 bits.

You can convert gigabit to other units of data on the following converters.

SI (The International System of Units) defines the prefix "kilo" to mean one thousand. Therefore:

1000 bits = 1 Kilobit (1 Kb)
1000 Kilobits = 1 Megabit (1 Mb) = 1 000 000 bits = 10^6 bits
1000 Megabits = 1 Gigabit (1 Gb) = 1 000 000 000 bits = 10^9 bits

However, since computers use the binary system, a different measurement is sometimes used:
1024 bits = 1 Kibibit (1 Kib)
1024 Kibibits = 1 Mebibit (1 Mib) = 1 048 576 bits = 2^20 bits
1024 Mebibits = 1 Gibibit (1 Gib) = 1 073 741 824 bits = 2^30 bits

As you can see, the SI-based units (Kilo, Mega, Giga...) are based on powers of ten.
The binary-based units (Kibi, Mebi, Gibi...) are based on powers of two.

What may cause confusion: Hard drive manufacturers use the SI units to denote sizes, e.g. 1 GB = 1 billion B, but Windows displays disk and file sizes in binary-based units, but written as GB instead of GiB! This means a 1 TB disk (1000 GB) appears to be 931.51 GB (1000 GiB)

Papacarlo, you're wrong. One gigabit is equal to 1,000,000,000 bits, you're talking about gibibit which is different.

This is wrong calculator. Use computer science and not a grocery store measurements. 1K=1024 so 1 gigabit = 1073741824 bits but not anyhow 1000000000 bits.
