  In order to test conversation of UOM,
-
  I convert Grams into TON with price.
-
  !python {model: product.uom}: |
    from_uom_id = ref("product_uom_gram")
    to_uom_id = ref("product_uom_ton")
    price = 2
    qty = 1020000
    price = self._compute_price(cr, uid, from_uom_id, price, to_uom_id)
    qty = self._compute_qty(cr, uid, from_uom_id, qty, to_uom_id)
    assert qty == 1.02, "Qty is not correspond."
    assert price == 2000000.0, "Price is not correspond."
