This free converter turns gigabit-per-second (Gbps) network and internet link speeds into megabits per second (Mbps) and back, and also shows the equivalent file-transfer throughput in MB/s. It’s handy for comparing fibre plans, switch ports, and data-centre uplinks quoted in different units.
How it works
Data transfer rates use decimal SI units, not the binary (1024) convention used for storage capacity. So the gigabit-to-megabit step is a simple factor of 1000:
Mbps = Gbps × 1000 (and Gbps = Mbps ÷ 1000)
To get real file throughput, the tool also divides the megabit figure by 8 (there are 8 bits in a byte):
MB/s = Mbps ÷ 8
Example
A 1 Gbps fibre line converts as follows:
- 1 × 1000 = 1000 Mbps
- 1000 ÷ 8 = 125 MB/s of actual file throughput
So a “1 gig” connection is 1000 Mbps, which moves data at about 125 megabytes per second before protocol overhead.
| Link speed | Mbps | MB/s (÷8) |
|---|---|---|
| 0.5 Gbps | 500 Mbps | 62.5 MB/s |
| 1 Gbps | 1000 Mbps | 125 MB/s |
| 2.5 Gbps | 2500 Mbps | 312.5 MB/s |
| 10 Gbps | 10000 Mbps | 1250 MB/s |
