HI
If we purchase a 20Mb leased line and we are downloading at 20Mb all month.
How much will we be able to download each month in total (on average)?
Thanks

Presuming you mean "20 megabytes per second"...
If you mean "20 megabits per second", that would be about 6TB. Normally you describe connection speed in megabits (Mb) rather than megabytes (MB). 


If you have no latency (eg: you are not in the real world physics of moving bits via light or electricity) then there are 2592000 seconds in 30 days, multiply by 20 megabits per second and you get 6.18 terabytes total. With physical latency and network traffic, really no way to know the real maximum. 


20 * 1024 * 1024 * 60 * 60 * 24 * 30 = 54,358,179,840,000 bits = 6.17 Terabytes. (Insert usual disclaimer about realworld vs theoretical limits, here.) 


20 mbit is:



MB/s or Mb/s? If it is MB/s then: 20MB/s * 60s/m * 60m/h * 24h/d * 30d/m = 51840000 MB (50625 GB) Since I think this is unrealistic I'm assuming you have a 20 Mb/s connection rate so: 51840000 Mb % 8b/B = 6480000 MB % 1024 MB/GB = 6328.125 GB (Theoretical limits at 100% usage of course ... real world doesn't apply here) 


Here is a calculator. It depends on what you mean by MB = megabytes or megabits per second. It could be either 54 Terabytes or 6.5 Terabytes worth of data per month, depending on what you mean. ( My guess the latter, cause otherwise you've got a very nice pipe, and I envy you :) This calculation assumes, you are utilizing it at full capacity 100 % of time, without any interruptions, no latency, and your pipes run on superconductors that are not susceptible to any interference. 


About 6.28 Tera a bytes (based on a 30 day month).
