4.1 Megabits

Why calculate? Connect to and measure your up/down speeds.

I tried a couple of those and they're both much slower than what I've acheived in downloading a real file. One was about 1.8 Mb/s the other 1.6 Mb. A couple of weeks ago, I managed to download a 102 MB file in just over 2 minutes. My cable connection is rated at 5 Mb/s down and 800 K up.

Depending on the web server used, the file may have been compressed during transmission resulting in a smaller transmission stream than 102 MB

When I saw how long it took I didn't believe it either. I tried again and the 2nd attempt wasn't much slower.

I really doubt your ISP is giving you 30% more bandwidth than you're paying for.

Speed tests depend on the remote computer being able to pump out data as fast or faster than you can receive it. Ditto the path from them to you. So these speeds test will not work if your connection is faster than the remote computer output or the path to you. So even if in theory both are faster than your connection, if their load is too much, you'll not get a good test.
