So to work out the speed of what your meant to be getting for internet you divide it by 8? so if you have 80MB connection you should be getting 10MB download speed? also how do you calculate upload speed?

Also can someone explain to me how 1gb can be 1024 MB and 1000MB I was always teach at college that 1mb was 1024 KB, 1gb was 1024MB and 1TB is 1024 GB can someone explain why people say it is 1000?

As far as I can tell that is correct...divide by 8 to find the speed you should actually be downloading...As for upload, divide by 8 as well?...They are being measured in the same unit, so wouldn't it make sence to divide by the same number?...That's what I THINK anyways...can someone confirm this?

People usually round it out (at least I do)...Its easier to remember\add\divide\whatever by 1000, then it is by 1024...Its also easier when your talking with someone who is not very, or at all, familiar with data units (tb, gb, mb, kb, etc)...Personlly I use 1000 all the time, but if you wanna be accurate, you should use 1024...
