Comprehensive units of measurement and quantity system for the ziegel framework. Provides strongly-typed quantities, unit conversions, and internationalized formatting for physical measurements.

Units & Measurements: Complete measurement system with type-safe quantities, unit conversion, and culture-aware formatting for scientific and engineering applications.

🚀 Overview

@breadstone/ziegel-intl-units provides:

• Quantity System: Strongly-typed quantities for Length, Mass, Area, Volume, Energy measurements
• Unit Conversion: Seamless conversion between metric, imperial, and custom unit systems
• Internationalized Formatting: Culture-aware display and formatting of measurements
• Type Safety: Full TypeScript support with interfaces and type guards
• Multiple Unit Systems: Support for metric, imperial, and custom measurement systems
• Extensible Architecture: Easy to add new units, quantities, and measurement types

📦 Installation

npm install @breadstone/ziegel-intl-units
# or
yarn add @breadstone/ziegel-intl-units

🧩 Features & Usage Examples

Length Quantities

import { LengthQuantity, LengthUnit, ILengthQuantity } from '@breadstone/ziegel-intl-units';

// Create and convert length measurements
const meters = new LengthQuantity(100, LengthUnit.Meter);
const feet = meters.convertTo(LengthUnit.Foot);
const inches = meters.convertTo(LengthUnit.Inch);

console.log(`${meters.value} m = ${feet.value} ft = ${inches.value} in`);

// Type checking with interfaces
function processLength(length: ILengthQuantity) {
  return length.convertTo(LengthUnit.Centimeter);
}

Mass and Weight

import { MassQuantity, MassUnit, IMassQuantity } from '@breadstone/ziegel-intl-units';

const kilograms = new MassQuantity(75, MassUnit.Kilogram);
const pounds = kilograms.convertTo(MassUnit.Pound);
const stones = kilograms.convertTo(MassUnit.Stone);

console.log(`${kilograms.value} kg = ${pounds.value} lbs = ${stones.value} st`);

// Type guards for validation
import { isMassQuantity } from '@breadstone/ziegel-intl-units';
if (isMassQuantity(someValue)) {
  // TypeScript knows someValue is IMassQuantity
  const grams = someValue.convertTo(MassUnit.Gram);
}

Area Measurements

import { AreaQuantity, AreaUnit, IAreaQuantity } from '@breadstone/ziegel-intl-units';

const squareMeters = new AreaQuantity(100, AreaUnit.SquareMeter);
const squareFeet = squareMeters.convertTo(AreaUnit.SquareFoot);
const acres = squareMeters.convertTo(AreaUnit.Acre);

console.log(`${squareMeters.value} m² = ${squareFeet.value} ft² = ${acres.value} acres`);

Volume and Capacity

import { VolumeQuantity, VolumeUnit, IVolumeQuantity } from '@breadstone/ziegel-intl-units';

const liters = new VolumeQuantity(50, VolumeUnit.Liter);
const gallons = liters.convertTo(VolumeUnit.Gallon);
const cubicFeet = liters.convertTo(VolumeUnit.CubicFoot);

console.log(`${liters.value} L = ${gallons.value} gal = ${cubicFeet.value} ft³`);

Energy Measurements

import { EnergyQuantity, EnergyUnit, IEnergyQuantity } from '@breadstone/ziegel-intl-units';

const joules = new EnergyQuantity(1000, EnergyUnit.Joule);
const calories = joules.convertTo(EnergyUnit.Calorie);
const kilowattHours = joules.convertTo(EnergyUnit.KilowattHour);

console.log(`${joules.value} J = ${calories.value} cal = ${kilowattHours.value} kWh`);

Internationalized Formatting

import {
  LengthQuantityFormat,
  MassQuantityFormat,
  AreaQuantityFormat,
  VolumeQuantityFormat,
  EnergyQuantityFormat,
} from '@breadstone/ziegel-intl-units';

// Format quantities with culture-specific formatting
const lengthFormatter = new LengthQuantityFormat('en-US');
const massFormatter = new MassQuantityFormat('de-DE');

const distance = new LengthQuantity(1500, LengthUnit.Meter);
const weight = new MassQuantity(75, MassUnit.Kilogram);

console.log(lengthFormatter.format(distance, 'short')); // "1500 m"
console.log(lengthFormatter.format(distance, 'long')); // "1500 meters"
console.log(massFormatter.format(weight, 'long')); // "75 Kilogramm"

Unit System Management

import { UnitSystem } from '@breadstone/ziegel-intl-units';

// Work with different unit systems
console.log(UnitSystem.Metric); // For metric system
console.log(UnitSystem.Imperial); // For imperial system
console.log(UnitSystem.US); // For US customary units

// Determine preferred units based on unit system
function getPreferredLengthUnit(system: UnitSystem) {
  switch (system) {
    case UnitSystem.Metric:
      return LengthUnit.Meter;
    case UnitSystem.Imperial:
      return LengthUnit.Foot;
    default:
      return LengthUnit.Meter;
  }
}
