How to convert gigabits per second to megabits per second
Mbit/s = Gbit/s × 1,000Multiply the value in gigabits per second by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A gigabit per second is larger than a megabit per second: one gigabit per second contains 1,000 megabits per second.
Worked examples
- 1 gigabit per second1 Gbit/s × 1,000 = 1,000 Mbit/s

About the units
Gigabit per second (Gbit/s)
One billion bits per second; fibre broadband and Ethernet ports are rated in Gbps. One gigabit per second equals 1,000,000,000 bits per second (bit/s).
Megabit per second (Mbit/s)
One million bits per second — the standard unit for broadband and Wi-Fi speeds. One megabit per second equals 1,000,000 bits per second (bit/s).
Frequently asked questions
How many megabits per second are in one gigabit per second?
There are 1,000 megabits per second in one gigabit per second, and this value is exact by definition.
How do I convert gigabits per second to megabits per second?
Multiply the number of gigabits per second by 1,000. For example, 10 Gbit/s × 1,000 = 10,000 Mbit/s.
How many gigabits per second are in one megabit per second?
One megabit per second equals 0.001 gigabits per second. That is the reverse factor, 1 ÷ 1,000.
What is 10 gigabits per second in megabits per second?
10 Gbit/s = 10,000 Mbit/s.
Is this Gbit/s to Mbit/s converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
