What this converter does
This converter turns gigabits per second into megabits per second and back. It also covers kbps, bps and byte-per-second rates. Because network speeds step by 1,000, one Gbps equals 1,000 Mbps. Type a value and read the result instantly.
Bits (lowercase b) measure link speed; bytes (uppercase B) measure file size, at eight bits each. This tool keeps them distinct, using the IEC decimal convention.
The units it covers
Every rate converts through bits per second; decimal steps of 1,000 (not 1,024) apply to network speeds.
View all units & their values
| Unit | Symbol | Value | Mainly used |
|---|---|---|---|
| Bit per second | bps | 1 | Base unit |
| Kilobit per second | kbps | 1,000 | Legacy modems, telemetry |
| Megabit per second | Mbps | 1,000,000 | Broadband, Wi-Fi |
| Gigabit per second | Gbps | 1e9 | Fibre, data-centre links |
| Byte per second | B/s | 8 | File-transfer speed |
The formula
Each unit has a fixed value in bits per second, so any conversion goes through bps once:
result = value × factor_from ÷ factor_toWhere:
- value = the number you typed
- factor_from = the “from” unit’s value in bps
- factor_to = the “to” unit’s value in bps
Worked example
Convert 10 Gbps to Mbps.
1 Gbps = 1,000 Mbps10 × 1000 = 10,000 MbpsSo a 10 Gbps link is 10,000 Mbps.
The units in this example
The unit of fibre and data-centre links. One gigabit is a billion bits per second.
- 1 Gbps = 1,000 Mbps
- 1 Gbps = 125 MB/s
- 1 Gbps = 1e6 kbps
- 10 Gbps = 10,000 Mbps
The everyday unit of broadband and Wi-Fi speed. One megabit is a million bits per second.
- 1 Mbps = 1,000 kbps
- 1 Mbps = 0.001 Gbps
- 1 Mbps = 0.125 MB/s
- 1,000 Mbps = 1 Gbps
