## Introduction

A Ruby Library for dealing with different types of unit conversion.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'convert_unit'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install convert_unit

## Usage

```ruby
require 'convert_unit'

meter = ConvertUnit::Length.new(1, 'km')
meter.to('km') #=> ConvertUnit::Length.new(1000, 'm')

# Comparisons
ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(1000, 'm')  #=> true
ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(1, 'm')     #=> false

ConvertUnit::Length.new(1, 'km') === ConvertUnit::Length.new(1, 'km')   #=> true
ConvertUnit::Length.new(1, 'km') === ConvertUnit::Length.new(1000, 'm') #=> false

# Arithmetic
ConvertUnit::Length.new(1, 'km') + ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(2, 'km')
ConvertUnit::Length.new(1, 'km') + ConvertUnit::Length.new(1000, 'm') == ConvertUnit::Length.new(2, 'km')
ConvertUnit::Length.new(1000, 'm') + ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(2000, 'm')
ConvertUnit::Length.new(1000, 'm') - ConvertUnit::Length.new(1, 'km') == ConvertUnit::Length.new(0, 'm')

# Valid units argument list
ConvertUnit::Length::UNITS_SYMBOL       #=> { "millimeter"=>"mm", "centimeter"=>"cm", "meter"=>"m",
                                        #     "kilometer"=>"km", "inche"=>"in", "feet"=>"ft", "yard"=>"yd", 
                                        #     "mile"=>"mi" }
                                        #
                                        # both short and full form are accepted in argument and case insensitive.

```
