UnitEase

A lightweight JavaScript library for unit conversion.

• Converts units for length, weight, temperature, and more.
• Supports both metric and imperial systems.

Example:

unitEase.convert(10, "meters", "feet");

---

Features

• Convert between various units for length, weight, temperature, and time.
• Check if a conversion is supported between two units.

---

Installation

UnitEase can be installed via npm:

npm install unitease

---

Usage

Import UnitEase

const UnitEase = require("unitease");

Convert Units

// Convert 10 kilograms to feet
const result = UnitEase.convert(10, "kilograms", "pounds");
console.log(result); // Output: 22.0462

Add Custom Conversion Definitions

// Add custom units and conversion factor.
// Add the factor for only one way calculation!
// Reverse factor will be automatically calculated.
UnitEase.addConversion("lightyears", "parsecs", 0.306601);
console.log(UnitEase.convert(2, "lightyears", "parsecs")); // Output: 0.613202

console.log(UnitEase.convert(2, "parsecs", "lightyears")); // Output: 6.5137

Add Custom Aliases

// Add custom aliases for any unit
UnitEase.addAlias("kilograms", "kg");
console.log(UnitEase.convert(5, "kg", "pounds")); // Output: 11.0231

Check Possible Conversions

// Get possible conversions for a temperature unit
console.log(UnitEase.getPossibleConversions("celsius"));
// Output: ['fahrenheit', 'kelvin']

Example Scenerios

1. Find all the valid conversions for a specific unit:

   const possibilities = UnitEase.getPossibleConversions("meters");
   console.log(`You can convert meters to: ${possibilities.join(", ")}`);
   // Output: You can convert meters to: feet, inches

2. Handle unsupported units gracefully:

   const possibilities = UnitEase.getPossibleConversions("lightyears");
   if (possibilities.length === 0) {
     console.log("No conversions available for this unit.");
   }
   // Output: No conversions available for this unit.

Check Conversion Support

// Check if a conversion from meters to feet is supported
const isSupported = UnitEase.supports("meters", "feet");
console.log(isSupported); // Output: true

Examples

// Length
console.log(UnitEase.convert(100, "meters", "feet")); // 328.084

// Weight
console.log(UnitEase.convert(5, "kilograms", "pounds")); // 11.0231

// Temperature
console.log(UnitEase.convert(100, "celsius", "fahrenheit")); // 212

// Time
console.log(UnitEase.convert(2, "hours", "minutes")); // 120

// Unsupported conversion
console.log(UnitEase.supports("kilograms", "miles")); // false

How It Works

1. The convert function checks the relevant unit type (length, weight, temperature, or time) and performs the conversion.

2. The supports function verifies if a conversion between the given units is possible.

3. The getPossibleConversions function lists all the units that a given unit can be converted to.
