Copper Price Per Gram Today

The copper price per gram is derived from the COMEX copper futures (HG) price, which is quoted in US cents per pound. To convert the per-pound price to a per-gram figure, divide by 453.592 (the number of grams in one avoirdupois pound). For example, if COMEX copper trades at $4.50 per pound, the per-gram price is approximately $0.00992, or just under one cent per gram. While this may seem like a trivially small number, the per-gram unit becomes highly relevant for industries and applications that deal in precise, small quantities of copper.

Electronics manufacturers are among the most frequent users of per-gram copper pricing. Printed circuit boards (PCBs) contain thin layers of copper foil, typically measured in grams per board. A standard smartphone PCB uses approximately 15-20 grams of copper, while a laptop motherboard may contain 30-50 grams. When a manufacturer produces millions of units, even fractional changes in the per-gram copper price translate into significant cost variations. PCB fabricators, connector manufacturers, and semiconductor packaging companies all track copper costs at the gram level to maintain accurate bill-of-materials pricing.

Fine wire producers represent another segment that relies on per-gram pricing. Copper magnet wire used in electric motors, transformers, and inductors is often sold by weight in small quantities, particularly for prototyping and specialty applications. Medical device manufacturers use ultra-fine copper wire measured in grams for components like MRI coils and surgical instruments. The per-gram price provides these buyers with the precision they need for cost estimation and procurement planning.

The craft and hobby market also benefits from per-gram copper pricing. Jewelry makers, metalworkers, and artists who purchase small quantities of copper sheet, wire, or granules often find per-gram pricing more intuitive than per-pound or per-tonne quotes. Copper clay (a material used in metal clay jewelry making) is sold by the gram, and understanding the raw copper value per gram helps crafters evaluate material costs against finished piece pricing.

On the London Metal Exchange (LME), copper is quoted in US dollars per metric tonne, which is the global wholesale standard. To convert from per-tonne to per-gram, divide by 1,000,000. The LME per-tonne price divided by 1,000 gives the per-kilogram price, and dividing again by 1,000 gives the per-gram figure. International copper traders regularly convert between per-pound (COMEX), per-tonne (LME), and per-gram units depending on the market and the buyer's requirements.
