It is a bottle, that is, a can. Listen is a foreign word from the English word tin. The original meaning is the abbreviation of tinplate box, which is a can made of tinplate, and later extended to a can, which is a unit of capacity.

The tin cans sold in supermarkets and the common apple juice are all apple vinegar. A can contains 330ml, which is 1ml= 1g according to the density of water. And 1 kg = 500g.

So 330g ÷ 500g = 0.66kg.
