Translate Mbps into the MB/s file applications display and compare theoretical plan transfer time with a measured 0bps download rate.
Only the measured Mbps field is filled from browser-local history.

COMMON QUESTIONS
Why is 100 Mbps only 12.5 MB/s?
Internet plans usually use megabits per second, while file applications often display megabytes per second. Eight bits make one byte, so the theoretical conversion is Mbps divided by eight.
Protocol overhead, server limits and shared network activity can make observed results differ from the theoretical result.
