How to convert Gbps to MB/s
Units (decimal, SI): kb = 1000 b, Mb = 1,000,000 b, Gb = 1,000,000,000 b. Also, 8 bits = 1 byte.
To convert Gbps to MB/s, first convert bits to bytes (divide by 8), then scale from gigas to megas (× 1000). This leads to the simplified formula:
Formula: MB/s = Gbps × 125.
Example: 2 Gbps × 125 = 250 MB/s.
Reverse conversion: Gbps = MB/s ÷ 125.

Understanding Gbps vs MB/s
Internet and network speeds are usually advertised in megabits or gigabits per second (Mbps, Gbps), while file sizes and download rates in apps are often shown in megabytes per second (MB/s).
Because there are 8 bits in a byte, and decimal prefixes use powers of 1000, 1 Gbps = 125 MB/s. For example, a 1 Gbps connection can theoretically transfer about 125 megabytes of data per second.
Real-world speeds are typically lower due to protocol overhead, Wi-Fi quality, server limits, and other network factors. This tool shows the ideal maximum conversion between Gbps and MB/s.
