Multi-Unit Dimension Converter

Build a comprehensive dimension and distance conversion tool that handles meters, kilometers, yards, feet, inches, miles, and other length measurements. This practical utility is essential for construction, travel planning, sports, and international commerce where different measurement systems are used.

What You'll Build:

An intuitive conversion application that provides instant translations between metric and imperial length units, featuring visual scale references and the ability to handle both small measurements (millimeters) and large distances (kilometers/miles).

Key User Stories:

• As a user, I want to convert meters to feet and yards instantly so that I can understand measurements in different systems
• As a user, I want to see live conversion updates as I type so that I can efficiently compare multiple unit values
• As a user, I want to convert between all length units including mm, cm, inches, and miles so that I can handle any measurement need
• As a user, I want to see visual scale references like "length of a football field" so that I can better understand the converted measurements
• As a user, I want to save and recall frequently used conversions so that I can quickly access common measurements
• As a user, I want to use the converter on mobile devices so that I can measure and convert while on-site or traveling

Technical Implementation:

Implement precise conversion algorithms using JavaScript with proper decimal handling for accuracy. Create a responsive interface that works across devices. Use local storage for saving user preferences and conversion history. Include validation for different input formats and edge cases.
