Megabits per Second to Gigabits per Second (Mbps to Gbps)
1 megabit per second (Mbps) = 0.001 gigabits per second (Gbps). 1 Gbps = 1000 Mbps. Example: 500 Mbps = 500 × 0.001 = 0.5 Gbps.

How to Convert Megabit per Second to Gigabit per Second
- 1 Mbps = 0.001 Gbps
- 1 Gbps = 1000 Mbps
- Example: convert 500 Mbps to Gbps: 500 Mbps = 500 × 0.001 Gbps = 0.5 Gbps
Formula
Gbps = Mbps ÷ 1000
Derivation from SI units:
- 1 Mbit/s = 10⁶ bit/s.
- 1 Gbit/s = 10⁹ bit/s.
- 1 Mbps = 1000000 bps ÷ 1000000000 bps per Gbps = 0.001 Gbps
Both units are defined exactly, so the factor is exact. Megabit per Second definition: megabit per second; Gigabit per Second definition: gigabit per second.
Worked examples
- A 500 Mbps plan is 0.5 Gbps.
500 Mbps × 0.001 = 0.5 Gbps - A 2500 Mbps link is 2.5 Gbps.
2500 Mbps × 0.001 = 2.5 Gbps

Frequently asked questions
Is a 1000 Mbps plan gigabit internet?
Yes: 1000 Mbps = 1 Gbps.
How many gigabits per second are in 1 megabit per second?
1 Mbps = 0.001 Gbps.
How do I convert megabits per second to gigabits per second?
Multiply the value in Mbps by 0.001, or divide it by 1000. For example, 500 Mbps × 0.001 = 0.5 Gbps.
Is the Mbps to Gbps conversion exact?
Yes. Both units are defined exactly, and 1 Mbps is exactly 0.001 Gbps.
