It's going to be hard to match it exactly, even when the download speed is stable.
A display of 40,000 in an interval (of 1 second) would imply 40 KBytes/sec
Short answer: 40 KB/s would be roughly right.
Long answer:
This is: 40 KB/s (or kB/s), but not kb/s
In kb/s, it would be 40 * 8 = 320 Kb/s
However, there are two other factors:
(1) Microsoft often uses K = 1024 even though in such uses, drives and networking, K = 1000 is more correct.
http://en.wikipedia.org/wiki/Kibibyte
I think IE (6.0 at least) uses K = 1024.
So this would be:
Same as: 320 * 1000/1024 = 312.5 Kib/s
Same as: 312.5 / 8 = 39.063 KiB/s
(2) The pure networking monitor measures all the data going across the wire. This includes the file data data, and also data for the management of TCP/IP and FTP or HTTP, etc., which is called "overhead". The IE dialog will typically only show the actual file data transfer rate.
Let's assume that around 4% of the network data is related to overhead.
Then, the full conversion for 40,000 Bytes / sec would be:
40,000 / 1024 = 39.063 KiB/s
Removing "4%" overhead, it would be: 39.063 / 1.04 = 37.56 KiB/s
Which Microsoft might display as "KB/s" instead of the more correct KiB/s.
So 40,000 bytes/s according to Task Manager -> "38 KB/s" according to I.E.
So, "40 KB/s" would be a good rough conversion here, but if you noticed a discrepency, the above can help you understand where the differences come from.
