MB/s to Mbps converter

This is the direction you need when checking whether you are getting what you pay for. A download manager reports MB/s because it is counting file bytes; your contract is in Mbps because that is how links are rated. Multiply the observed MB/s by eight and compare.

Expect the comparison to fall short even on a healthy connection. Protocol overhead costs ten to fifteen per cent before anything else, so a genuinely good 100 Mbps line shows around 11 MB/s rather than the theoretical 12.5. If you are seeing 11.2 MB/s on a 100 Mbps line, that is the line performing correctly, not underperforming.

A large shortfall usually is not the line. In order of likelihood: the server capping per-connection speed, wifi rather than ethernet, an old router, or the device’s own disk. A speed test measures the line specifically and rules the rest out — which is why a speed test result and a download speed disagreeing is normal rather than suspicious.
