How to convert Mbps to MB/s
Divide megabits per second by eight to get megabytes per second because every byte contains eight bits. A 100 Mbps internet connection therefore has a theoretical maximum rate of 12.5 MB/s.
Quick reference
Common Mbps and Gbps conversions
| Network rate | Megabytes/sec | Gigabytes/sec |
|---|---|---|
| 10 Mbps | 1.25 MB/s | 0.00125 GB/s |
| 100 Mbps | 12.5 MB/s | 0.0125 GB/s |
| 1 Gbps | 125 MB/s | 0.125 GB/s |
| 2.5 Gbps | 312.5 MB/s | 0.3125 GB/s |
| 10 Gbps | 1,250 MB/s | 1.25 GB/s |
Read the capitalization
Bits, bytes, and unit prefixes
Lowercase b: bits
Mbps and Gbps describe millions or billions of bits per second. Network links and internet plans usually use these units.
Uppercase B: bytes
MB/s and GB/s describe bytes per second. File transfers and storage tools commonly display these units.
Decimal prefixes
Kilo, mega, and giga use powers of 1,000 for networking rates. One MB/s is exactly 8 Mbps in decimal units.
Binary byte units
KiB/s, MiB/s, and GiB/s use powers of 1,024. They are included when software reports binary transfer rates.
Theoretical rates
Converted speed is not guaranteed throughput
Unit conversion is exact, but real transfer speed can be lower because of protocol overhead, congestion, Wi-Fi quality, server limits, storage performance, VPNs, and other traffic. Use the converted value as the theoretical rate for the entered bandwidth.
Common questions
Bandwidth conversion FAQ
How do I convert Mbps to MB/s?
Divide Mbps by eight. For example, 100 Mbps equals 12.5 MB/s.
How many MB/s is 1 Gbps?
One gigabit per second equals 125 decimal megabytes per second.
What is the difference between MB/s and MiB/s?
MB/s uses 1,000,000 bytes per megabyte; MiB/s uses 1,048,576 bytes per mebibyte.
