Unit Converter is a PHP library that makes unit converting a fairly simple an intuitive process.
$ composer require skoyah/unit-converterThe Unit Converter library is under Skoyah\Converter namespace.
Once you have installed the Unit Converter library, converting from one unit of measurement to another is really simple.
First, create a new instance of the desired type and import the related class. The instance needs to accept two parameters - 1) a boolean for the quantity, and 2) a string for the unit of measurement.
Next, all you need is to call a to() method and pass in the parameter for the convertion.
use Skoyah\Converter\Mass;
$mass = new Mass(1, 'kg');
echo $mass->to('pounds'); // '2.20462262'Alternatively, you can convert using the unit abbreviation as a parameter:
echo $mass->to('lbs'); // '2.20462262'The to() method has also an optional parameter tor defining how many decimal units should be displayed for the given convertion.
echo $mass->to('lbs', 2); // '2.20'Currently, the Unit Converter supports the following types:
During instantiation or convertion, you have two options for defining the unit to be used.
There is a longform and a short-hand word available for each unit of measure.
For consistency, it is recommended to use lowercase letters, but if you prefer you can use uppercase letters since during instantiation and/or convertion, the unit of measure will be parsed and formatted to lowercase characters.
