Correct Number Units plugin

Plugin details

This plugin corrects everything in Rails, including the number_to_human_size helper of ActiveView. It is to be used by people who believe in standards and who respect their users enough not to show numbers measured in wrong units.

The Rails framework prides itself on being very strict about things like the HTTP protocol (cleary seen in the excellent REST implementation), testing practices, MVC (model-view-controller) separation and more. This is why some people were surprised to see that number conversion methods of ActiveSupport like "1.kilobyte" or "1.megabyte" still measure in wrong units.

A kilobyte is 1000 bytes, not 1024 like the current implementation. This inconsistency has been the source of many confusion and lawsuits (typical companies sued were those who advertise hard-disk capacity in wrong units). The article that sums this up nicely can be found on:

What is 1024 bytes, then? Well, 1024 bytes is a "kibibyte". Following that is "mebibyte", "gibibyte" and so on. Those prefixes indicate that we are measuring in base 2 units (the powers of 2). "Kilo" and "mega" were always stricly powers of 10.
