Gigabits per second to Megabits per second Converter Gbit/s → Mbit/s

1 gigabit per second (Gbit/s) = 1000 megabits per second (Mbit/s). Type a value below — the conversion happens instantly, entirely on your device.

From

1 Gbit/s = 1000 Mbit/s

Precision

1 gigabits per second = 1000 megabits per second

1 × 1000 = 1000

1 Gbit/s equals 1000 Mbit/s, so multiplying by 1000 converts the value. The result describes the exact same quantity — only the measuring stick changes.

How to convert gigabits per second to megabits per second

megabits per second = gigabits per second × 1000 — multiply the gigabit per second value by 1000.

Example: 1 Gbit/s = 1000 Mbit/s.

To convert the other way: gigabits per second = megabits per second ÷ 1000 — or use the dedicated Mbit/s to Gbit/s converter .

One gigabit per second is exactly 1,000 megabits per second — a straight ×1000, since these are both decimal SI units. "Gigabit internet" is 1,000 Mbps; a 2.5 Gbps port is 2,500 Mbps.

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 megabit per second?

A megabit per second is 1,000,000 bits/s — the unit internet plans are sold in ("100 Mbps"). Divide by 8 for megabytes per second.

Frequently asked questions

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

1 gigabit per second (Gbit/s) = 1000 megabits per second (Mbit/s).

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

megabits per second = gigabits per second × 1000 — multiply the gigabit per second value by 1000.

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

Multiply by 1000 for a close estimate. Exact factor: 1 Gbit/s = 1000 Mbit/s.

Is this Gbit/s-to-Mbit/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.
