Gigabits per second to Gigabytes per second Converter Gbit/s → GB/s

1 gigabit per second (Gbit/s) = 0.125 gigabytes per second (GB/s). Type a value below — the conversion happens instantly, entirely on your device.

From

1 Gbit/s = 0.125 GB/s

Precision

1 gigabits per second = 0.125 gigabytes per second

1 × 0.125 = 0.125

1 Gbit/s equals 0.125 GB/s, so multiplying by 0.125 converts the value. The result describes the exact same quantity — only the measuring stick changes.

How to convert gigabits per second to gigabytes per second

gigabytes per second = gigabits per second × 0.125 — multiply the gigabit per second value by 0.125.

Example: 1 Gbit/s = 0.125 GB/s.

To convert the other way: gigabits per second = gigabytes per second ÷ 0.125

Gigabits per second to gigabytes per second is again a divide-by-8: a 1 Gbps link moves 0.125 GB/s (125 MB/s) of actual data. Fibre and 10G Ethernet are rated in Gbps; storage throughput is usually in GB/s.

About the units

What is a gigabit per second?

A gigabit per second is 1,000 Mbps — the speed of fibre plans and Ethernet ("gigabit internet"). One Gbps is 125 MB/s.

What is a gigabyte per second?

A gigabyte per second is 8 Gbps (1,000,000,000 bytes/s) — the realm of SSDs and memory buses rather than internet links.

Frequently asked questions

How many gigabytes per second are in 1 gigabit per second?

1 gigabit per second (Gbit/s) = 0.125 gigabytes per second (GB/s).

What is the formula to convert gigabits per second to gigabytes per second?

gigabytes per second = gigabits per second × 0.125 — multiply the gigabit per second value by 0.125.

How do I convert Gbit/s to GB/s without a calculator?

Multiply by 0.125 for a close estimate. Exact factor: 1 Gbit/s = 0.125 GB/s.

Is this Gbit/s-to-GB/s converter accurate and private?

Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.
