What this converter does
This converter turns megabits per second into gigabits per second and back. It also covers kbps, bps and byte-per-second rates. Network speeds use decimal steps of 1,000, so 1 Gbps is exactly 1,000 Mbps. Type a value and read the result as you type.
Bits (lowercase b) measure link speed; bytes (uppercase B) measure file size — one byte is eight bits. This tool keeps them straight, following 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 2,500 Mbps to Gbps.
1 Gbps = 1,000 Mbps2500 ÷ 1000 = 2.5 GbpsSo a 2,500 Mbps link is a 2.5 Gbps connection.
The units in this example
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
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
