How to Convert Mbps to Gbps
Formula: Gbps = Mbps ÷ 1,000
1 Gbps = 1,000 Mbps. Network speeds use decimal (base-10) prefixes, unlike data storage which uses binary (base-2).
| Mbps | Gbps |
|---|---|
| 1 Mbps | 0.001 |
| 5 Mbps | 0.005 |
| 10 Mbps | 0.01 |
| 25 Mbps | 0.025 |
| 50 Mbps | 0.05 |
| 100 Mbps | 0.1 |
| 200 Mbps | 0.2 |
| 300 Mbps | 0.3 |
| 400 Mbps | 0.4 |
| 500 Mbps | 0.5 |
| 600 Mbps | 0.6 |
| 700 Mbps | 0.7 |
| 800 Mbps | 0.8 |
| 900 Mbps | 0.9 |
| 1,000 Mbps | 1 Gbps |
| 2,000 Mbps | 2 Gbps |
| 2,500 Mbps | 2.5 Gbps |
| 5,000 Mbps | 5 Gbps |
| 10,000 Mbps | 10 Gbps |
When You Need This Conversion
Internet plans: Basic broadband starts at 25 Mbps. The average US home connection is around 100 Mbps. Gigabit fiber delivers 1,000 Mbps (1 Gbps). ISPs market speeds in Mbps or Gbps depending on what sounds more impressive.
Streaming requirements: 4K Netflix needs about 25 Mbps. 8K streaming requires roughly 100 Mbps. Multiple simultaneous streams multiply these requirements.
Network infrastructure: Data center links operate at 10–100 Gbps. Enterprise switches commonly support 1 Gbps, 10 Gbps, or 25 Gbps per port.

When to use this
Your ISP is advertising a "1 Gbps" plan and you want to know how that compares to your current 300 Mbps connection. Or you are speccing out network switches for an office and need to convert between megabit and gigabit ratings to compare equipment. This converter translates between Mbps (megabits per second) and Gbps (gigabits per second) — the two most common units for describing network and internet speeds.
The conversion is straightforward: divide Mbps by 1,000 to get Gbps, or multiply Gbps by 1,000 to get Mbps. So 500 Mbps = 0.5 Gbps, and 2.5 Gbps = 2,500 Mbps. While the math is simple, having a converter is useful when comparing plans, reading spec sheets, or quickly translating between units during a conversation with your IT team or internet provider.
Good to know
Mbps uses base-10 (decimal), not base-2. In networking, 1 Gbps = 1,000 Mbps (not 1,024). This follows the SI prefix system. Storage uses the binary system (where 1 GB = 1,024 MB in some contexts), but network speeds consistently use decimal prefixes. Do not confuse the two.
Bits and bytes are different. Internet speeds are measured in bits per second, but file sizes are measured in bytes. There are 8 bits in a byte. So a 1 Gbps connection can theoretically transfer 125 megabytes per second (1,000 Mbps / 8), not 1,000 MB/s. When your ISP says 100 Mbps, your maximum download speed is about 12.5 MB/s — which is why your downloads seem slower than the advertised speed.
Real-world speeds are lower than advertised. Protocol overhead, network congestion, Wi-Fi interference, and server limitations mean you rarely get 100% of your rated speed. A "gigabit" connection typically delivers 800–950 Mbps over a wired Ethernet connection and 400–700 Mbps over Wi-Fi, depending on your router and environment.
