How to get the Unit of measure label of product attributes like weight,Length etc in product detail page?

Answer 1

This settings comes from system configuration.

Weight: Stores -> Configurations -> Generale -> Locale Options -> Weight Unit

use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Store\Model\ScopeInterface;

Then

/**
 * @var ScopeConfigInterface
 */
private $scopeConfig;

/**
 * @param ScopeConfigInterface $scopeConfig
 */
public function __construct(ScopeConfigInterface $scopeConfig)
{
    $this->scopeConfig = $scopeConfig;
}

Get value:

$weightUnit = $this->scopeConfig->getValue(
        'general/locale/weight_unit',
        ScopeInterface::SCOPE_STORE
    );

For dimension (width, length): here is the logic

vendor/temando/module-shipping-m2/Ui/DataProvider/Product/Form/Modifier/Dimensions.php

($weightUnit === 'kgs') ? 'cm' : 'in'
