This calculator caters for the IEC standard prefixes for binary sizes introduced in 1999. The data transfers can be specified
in either the 1024 byte 'k' as well as the 1000 byte variant. This approach has been adopted as most (if not all) router manufacturers
use 106 (1,000,000) as the size of a 'mega byte' rather than 220 (1048576). However, as Zen use the 220 version when describing data
allowances etc, I have catered for both variants. Please note that, as far as I am aware, all ISPs and router manufacturers use a
1000 byte 'k' when referring to kbps speeds so that is the only variant offered for down load speed.

More information about the standards can be found here:

This calculator can be run on your own PC/Server.
Just view the page source, copy it, and then save it to a file of your own name e.g. "DLoadCalc.html".
Edit the file to remove the header & footer sections (clearly marked in the file) and then place it
into file store on your own PC/Server. To use just point your browser to the file and open it.
