To convert Mbps to Gbps, divide by 1,000. 1 Gbps = 1,000 Mbps, so 500 Mbps = 0.5 Gbps and 100 Mbps = 0.1 Gbps. Network speeds always use decimal (SI) prefixes, never 1,024.
Formula
Gbps = Mbps ÷ 1,000. Mbps = Gbps × 1,000. Both are bits per second: 1 Mbps = 1,000,000 bits/s and 1 Gbps = 1,000,000,000 bits/s.
Mbps to Gbps table
| Mbps | Gbps |
|---|---|
| 1 Mbps | 0.001 Gbps |
| 10 Mbps | 0.01 Gbps |
| 50 Mbps | 0.05 Gbps |
| 100 Mbps | 0.1 Gbps |
| 200 Mbps | 0.2 Gbps |
| 300 Mbps | 0.3 Gbps |
| 500 Mbps | 0.5 Gbps |
| 1,000 Mbps | 1 Gbps |
| 2,500 Mbps | 2.5 Gbps |
| 10,000 Mbps | 10 Gbps |
Mbps vs MB/s
A lowercase b means bits, uppercase B means bytes (8 bits). A 1 Gbps plan moves at most 1,000 ÷ 8 = 125 MB/s before protocol overhead. See Mbps to MB/s.
How long does 1 GB take on 1 Gbps?
1 GB = 8,000,000,000 bits. 8,000,000,000 ÷ 1,000,000,000 = 8 seconds at a steady 1 Gbps with no overhead. Try other sizes in the download time calculator.

FAQ
How many Mbps is 1 Gbps?
1 Gbps equals 1,000 Mbps. Network speeds use decimal prefixes, so it is 1,000, not 1,024.
Is 1000 Mbps the same as 1 Gbps?
Yes. 1,000 Mbps ÷ 1,000 = 1 Gbps.
How do I convert Mbps to Gbps?
Divide the Mbps value by 1,000. For example, 300 Mbps ÷ 1,000 = 0.3 Gbps.
How many MB per second is 1 Gbps?
1 Gbps is 125 megabytes per second (1,000 Mbps ÷ 8), before protocol overhead.
Is Gbps faster than Mbps?
A gigabit per second is 1,000 times a megabit per second, so 1 Gbps is 1,000 times faster than 1 Mbps.
