How to display the name of the weight unit in opencart 3?

Question

opencart

There are weight units in the admin panel, I added the necessary ones, I try to display the latest (new arrivals) in the native plugin, for this I did:

1) controller 2) twig I get the result, but not the one, instead of the name of the unit (for example - kg / g / l / ml ) I get its ordinal number (1/2/3/4....) How can I display the name of the weight unit?
'weight_class' => $result['weight_class_id'],
{{product.weight_class}}

Answer 1

I found it, take it to whoever needs it,

'weight'      => (float)$result['weight'],  //(вывели сам вес (численное значение с округлением))
'unit'        => $this->weight->getUnit($result['weight_class_id']), // (а тут вывели наименование его единицы веса)

In twig:
Вес: {{weight}} {{unit}}
