Answer 1

public function getStoreWeightUnit($storeId) {

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

$unit = ($weightUnit == 'grams') ? 'GRAMS' : (($weightUnit == 'kbs') ? 'KILOGRAM' : 'LBS');

return $unit;
