Fundamental Concepts

Unit Hierarchy

Systems must define base units (meters, seconds) and derive complex units (velocity = meter/second). This forms the foundation for advanced calculations.

Conversion Logic

Implement scalable conversion algorithms that handle base-to-derived unit translations while preserving measurement accuracy across scales.

Design Implementation

1

Base Definition

Create core measurement units with validation for decimal precision and unit scaling.

// Base measurement definition\nclass MetricUnit {\n    constructor(symbol, baseValue = 1) {\n        this.symbol = symbol;\n        this.baseValue = baseValue;\n    }\n\n    convertTo(value, targetUnit) {\n        return value * (this.baseValue / targetUnit.baseValue);\n    }\n}\n

2

Compound Metrics

Build derived units using combinations of base measurements.

// Create base units\nconst meter = new MetricUnit('m', 1);\nconst kilometer = new MetricUnit('km', 1000);\nconst second = new MetricUnit('s');\n\n// Derive velocity unit\nconst velocity = (distance, duration) => {\n    return distance.value / duration.value;\n};

* This demo supports basic metric conversions but would be extended with additional unit types (time, mass, etc.) for production systems

Challenge: Create Unit System

Implement a unit system for thermal measurements with the following requirements:

Define base unit: Kelvin
Create derived units: Celsius and Fahrenheit
Implement triple point of water conversion

class ThermometricUnit extends MetricUnit {\n    constructor(symbol, offset = 0, scale = 1) {\n        super(symbol, 1);\n        this.offset = offset;\n        this.scale = scale;\n    }\n\n    convertTo(value, targetUnit) {\n        return (value - this.offset) * this.scale / targetUnit.scale + targetUnit.offset;\n    }\n}\n\n// Usage\nconst kelvin = new ThermometricUnit('K');\nconst celsius = new ThermometricUnit('°C', -273.15);\nconst fahrenheit = new ThermometricUnit('°F', -459.67, 5/9);
