The prices seen on the futures software are all unit prices, which is 1 ton in the words of your question. But it should be noted that not all goods are calculated in tons.

That is, for example, copper is 5 tons per hand, and the software shows 40000. It means 40,000 yuan/ton, and the transaction is 5 tons. That is, the transaction scale reaches 40,000 yuan x 5 = 200,000 yuan. If the margin rate is 10%, it is 20,000 yuan for primary copper.

The unit of each variety is different, such as copper and zinc 5 tons/hand, white sugar rubber 10 tons/hand, silver 15 kg/hand, and eggs 500 kg/hand.

What is the specific unit of each variety? You can see the background introduction (F 10) in the software, which contains standard contract data and is written in the data.
