README

        
# This library aims to provide effective parsing of user-supplied measures/metrics, intuitive scaling of those

# measures into a standard base scale unit and intuitive presentation of values.  It does not attempt to mixin

# unit-oriented methods into Ruby standard classes -to perform operations, particularly across dimensions, you

# will need to use basic conversion methods provided by this library combined with standard Ruby numerical oper-

# ations.  There is no method_missing magic or large mixin of spiffy unit-like methods here.

#

# Here are some examples of what you can do with the Dimensional library:

#

# require 'dimensional'

# require 'test/demo'

# class Autonomy < Dimensional::Metric

#   self.dimension = Dimensional::Dimension::L

# end 

# range = Autonomy.parse("15 nautical miles")

# range.to_s	# => "15M"

# range.base  # => >

# range.base.to_s # => "27780m"

# usrange = range.convert(Dimensional::Unit[:L, :US, :yd])	# => <30380.5774278215 >

#

# The demo library in the test directory contains a good starter set of units.

#

# The long-term objective for this library is to achieve compliance with the UCUM standard.  References:
