A simple unite converter library

Installation

Install the package via composer:

composer require lase-peco/unit-converter

Then publish the config file conversions.php with the following command

php artisan vendor:publish --provider="LasePeCo\UnitConverter\ServiceProvider"

The config file conversions.php contains all units of measurement and its values.

Define your own units

First add your unit in the config file und the matching section, then it is recommended to create a class That extends the base package class.

Example: Say you want to add KM^2 as an Area unit, first add the unit in the config file:

'area' => [
        'mm^2' => 1000000,
        'm^2' => 1, // base unit.
        'ft^2' => 10.7639,
        'yd^2' => 1.19598888894151,
        'km^2' => 0.000001, // your new unit and its value compared to the base unit.
    ],

Then create Area class in App\Units\ which should extends the base Area class of this package:

<?php
namespace App\Units;
use LasePeCo\UnitConverter\Units\Area as BaseArea;

class Area extends BaseArea
{
    public const SquareKiloMeter = 'km^2';
}

We recommend using these classes to avoid typos in your code.

Usage

This package supports 4 measuring systems Metrics, UK, US feet and US yards.

To get all supported measuring systems you can call the function getSupportedSystems() on the Converter facade.

use LasePeCo\UnitConverter\Facades\Converter;

Converter::getSupportedSystems(); 

// return

 [
  'metrics'  => 'Metrics',
  'uk'       => 'UK',
  'us_feet'  => 'US feet',
  'us_yards' => 'US yards'
 ]

This package is also able to convert area, density, length, mass, volume, volumetric flow rate and speed, these are functions you can call on the Converter facade. Each of them have its own class where the units are defined as constants, to provide some strong typing.

All of these functions accept the same parameters:

string $from_unit the unit, from which you are converting. string $to_unit the unit, to which you are converting. float $measurement the value. int $decimals (optional) the decimal accuracy. default is 2.

Area

The implemented area units are: SquareMillimeter, SquareMeter, SquareFoot, SquareYard.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\Area;

Converter::area(Area::SquareKiloMeter, Area::SquareMeter, 1); // return 1000000
Converter::area(Area::SquareMeter, Area::SquareYard, 10, 4); // return 11.9599

Density

The implemented density units are: KilogramPerCubicMeter, TonPerCubicMeter, PoundPerCubicFoot.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\Density;

Converter::density(Density::KilogramPerCubicMeter, Density::PoundPerCubicFoot, 1, 6); // return 0.062428

Length

The implemented length units are: Millimeter, Meter, Inch.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\Length;

Converter::length(Length::Meter, Length::Inch, 1, 4); // return 39.3701

Mass

The implemented mass units are: Kilogram, Ton, ImperialTon, USTon, Pound, Gram, Ounce.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\Mass;

Converter::mass(Mass::Kilogram, Mass::Pound, 1); // return 2.2

Volume

The implemented volume units are: CubicDecimeter, CubicMeter, CubicFoot, CubicYard.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\Volume;

Converter::volume(Volume::CubicMeter, Volume::CubicFoot, 1); // return 35.31

Speed

The implemented speed units are: MillimeterPerSecond, MeterPerSecond, FootPerSecond, YardPerSecond.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\Speed;

Converter::speed(Speed::MeterPerSecond, Speed::FootPerSecond, 1); // return 3.28

Volumetric flow rate

The implemented volumetric flow rate units are: CubicDecimeterPerHour, CubicMeterPerHour, CubicFootPerHour, CubicYardPerHour.

use LasePeCo\UnitConverter\Facades\Converter;
use App\Units\VolumetricFlowRate;

Converter::volumetric_flow_rate(VolumetricFlowRate::CubicMeterPerHour, VolumetricFlowRate::CubicDecimeterPerHour, 1)); // return 1000
