RE: help me guysTon = 2000 lbs. American/imperial system.
Tonne = 1000kg. Metric - the system the rest of the world uses, including the LME.
I assume you mean the LME not the LSE, since the LME is where metals trade.
Copper prices are already about $9,000/tonne... so $2,000 isn't much of a prediction. Unless that was a typo and they meant $20,000/tonne.
