Do you want to measure the time before or after you download ?

if before, your 750k ADSL might give you something between 60 and 75 KB/s (may vary depending on your line quality and your distance from the ISP's POP and the load on the server you are trying to download from, and the congestion on the ISP's uplink, ...). So you might get the 10mb file in about 2-3 minutes.

if after, you can use a program like "wget" which can give you the time it took for the download.

the answer matey


Take your download speed

Mine = 600kb

Now this is the usually "hidden" bit. To make their connection sound better than the rest, ISPs calcualte bandwith in KiloBits per second, and the rest of the world works in kilobyes per second

To convert from megabits to megabytes:

Number of megabits per second

Now take the download size and multiply it by 1000, to convert it to kilobytes

Divide the download size by the download speed, then multiply by 60 to get the number on mins needed for the download.

Example: my connection in 600kb per sec

600/8 = 70 kiloBYTES a sec

download size : 700mb

700*1000 = 700,000 kilobytes

700,000 / 75 = 9333.33

9333.3333 / 60 = 155.55

155 mins so 2 and a half hours
