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

1 megabit per second (Mbit/s) = 0.001 gigabits per second (Gbit/s). Type a value below — the conversion happens instantly, entirely on your device.

From

1 Mbit/s = 0.001 Gbit/s

Precision

500 megabits per second = 0.5 gigabits per second

500 × 0.001 = 0.5

1 Mbit/s equals 0.001 Gbit/s, so multiplying by 0.001 converts the value. The result describes the exact same quantity — only the measuring stick changes.

How to convert megabits per second to gigabits per second

gigabits per second = megabits per second × 0.001 — multiply the megabit per second value by 0.001.

Example: 500 Mbit/s = 0.5 Gbit/s.

To convert the other way: megabits per second = gigabits per second ÷ 0.001 — or use the dedicated Gbit/s to Mbit/s converter .

Megabits to gigabits divides by 1,000: a 500 Mbps plan is 0.5 Gbps, and 1,000 Mbps is exactly 1 Gbps. Handy when comparing a fast cable plan against fibre quoted in gigabits.

About the units

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.

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.

Frequently asked questions

How many gigabits per second are in 1 megabit per second?

1 megabit per second (Mbit/s) = 0.001 gigabits per second (Gbit/s).

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

gigabits per second = megabits per second × 0.001 — multiply the megabit per second value by 0.001.

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

Multiply by 0.001 for a close estimate. Exact factor: 1 Mbit/s = 0.001 Gbit/s.

Is this Mbit/s-to-Gbit/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.
