Mbits/s CONFUSED

Don't trash the thread guys, it was a genuine question. This isn't GD!

Here's a good conversion tool..

Rule of thumb.. small font = bits, LARGE FONT = BYTES.

so 8MB = 8 Mega Bytes.

Hard drive/file sizes in Windows are reported in Bytes. In networking, it's reporting in bits.

Mbps/8 = KB/s = MB/s

50 Mbps / 8 = 6250 KB/s = 6.25 MB/s...

6250 KBs / 1024 KBs per MB = 6.10 MBs

Ah, you might be right. Damn it.

Well actually 50Mbit provides a theoretical 6.25MB/sec transfer rate (50/8=6.25). It's the 6250KB/sec part that's wrong as theoretically the maximum is actually 6400KB/sec (1Mbit is 128KB so 50Mbit is 6400KB).

However in reality about 6200KB/sec is more realistic after overheads anyway.

And then some smart-alec comes along and starts talking about MiBs and how the accepted terminology is all wrong.

To the OP, if you connection is 20megabit, and your provider of news quotes 10 megabit, then surely it's obvious that you just halve your calculated speed? So you'd likley get 2.3/2 = 1.15MB a sec? (which is near as dammit bang on AFAICT)
