Physical Fields

Provides an API for storing and manipulating physical measurements.

Supports unit conversions.

Drupal 8

Supported measurement types:

• Area
• Length
• Temperature
• Volume
• Weight

Provided field types:

• Physical measurement: Stores a single measurement and its unit.
• Physical dimensions: Stores the length/width/height measurements and their unit.

Other features:

• Language-specific number input and formatting
• Value objects with support for bcmath-based arithmetic.

Example:
<?php
use Drupal\physical\Weight;
use Drupal\physical\WeightUnit;

$weight = new Weight('100', WeightUnit::KILOGRAM);
$other_weight = new Weight('120', WeightUnit::KILOGRAM);
// Add the two weights together then express them in pounds.
$new_weight = $weight->add($other_weight)->convert(WeightUnit::POUND);
?>
