### Namespacing

[](#namespacing)

The 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.

### Example conversion:

[](#example-conversion)

```
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'
```

Support
-------

[](#support)

Currently, the Unit Converter supports the following types:

- [Mass](#mass-units)
- [Temperature](#temperature-units)
- [Length](#length-units)
- [Pressure](#pressure-units)
- [Area](#area-units)
- [Volume](#volume-units) - ***New***

Configuration
-------------

[](#configuration)

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.
