LME COPPER PRICE CALCULATOR
Convert the LME copper cash settlement between USD per tonne, USD per pound and your local currency. Always shows the source, units and timestamp.
Conversion formulas
USD/lb = USD/t ÷ 2204.62262185. Local price = USD/t × FX rate. MetalPulse keeps LME (USD/t) and COMEX (USD/lb) as separate rows — never mixed — to preserve basis differences.
LME vs COMEX
LME copper trades in USD/tonne with three-month forward as the benchmark; COMEX trades in USD/lb on US futures. The basis difference (a few cents/lb) is a tradable signal.
Worked example
LME copper $9,200/t → $9,200 ÷ 2204.62262185 = $4.173/lb. At USD/ZAR 18.5 → R170,200/t.
Key assumptions
- 1 tonne = 2,204.62262185 lb
- FX rate is mid-market
