Mbps to MB/s Converter

Divide megabits per second by 8. Internet plans are sold in bits per second, but browsers, Steam and file managers show downloads in bytes per second, and a byte is 8 bits. A 300 Mbps plan can move at most 300 ÷ 8 = 37.5 MB/s.

Watch the letter case: a small b means bits (Mb, Mbps), a capital B means bytes (MB, MB/s). Some download tools also use binary mebibytes, so the same 300 Mbps can appear as 35.76 MiB/s.

Real downloads come in below the line speed, because every packet carries headers, Wi-Fi adds its own overhead, and the server at the other end may be the slower side. Treat the converted figure as a ceiling, not a promise.

Halve three times: 200 Mbps → 100 → 50 → 25 MB/s. Or divide by 10 for a slightly pessimistic figure that already allows for some overhead: 200 Mbps gives “about 20 MB/s”.

To guess a download time, multiply the file size in GB by 8,000 and divide by your Mbps: a 50 GB game at 100 Mbps takes at least 4,000 seconds, a little over an hour.
