Data Methodology

Where does this price data come from?
Copper spot prices are sourced from Metals.Dev, a professional metals data provider, with automatic fallback to gold-api.com for redundancy. Prices are updated in real-time during market hours, ensuring you always see the latest data. All prices reflect the latest available mid-market spot rate.
How is the copper spot price determined?
The copper spot price is derived from the most actively traded futures contracts on COMEX (CME Group) and the London Metal Exchange (LME). The spot price represents the current market price for immediate delivery, calculated from near-month futures contracts adjusted for carry costs. During off-hours, prices reflect OTC (over-the-counter) trading across global markets, providing continuous 24-hour price discovery.
How is the unit conversion calculated?
The displayed price uses a conversion multiplier of 0.06857153565318613 applied to the per-troy-ounce spot price. One troy ounce equals 31.1035 grams.
When are precious metals markets open?
COMEX futures trade Sunday through Friday, 6:00 PM to 5:00 PM ET (23 hours per day with a 1-hour break). The London Bullion Market (LBMA) operates Monday to Friday with two daily fixings: AM fix at 10:30 AM London time and PM fix at 3:00 PM London time. Outside of formal exchange hours, precious metals continue to trade on OTC markets globally, meaning prices can move 24 hours a day, 5 days a week. Our data reflects these continuous market movements.

Copper Price Per Troy Ounce

Copper is traditionally quoted per pound (in the U.S.) or per metric tonne (internationally), but many precious metals investors and bullion buyers prefer the per-troy-ounce measurement used for gold, silver, and platinum. This page converts the live copper spot price to troy ounces for easy comparison with other metals. One troy ounce of copper weighs 31.1035 grams, approximately 0.0686 pounds, so the per-ounce price is roughly 6.86% of the per-pound price.

Copper bullion coins and rounds have become increasingly popular among collectors and stackers who value the metal's industrial importance and affordability. Well-known copper bullion products include one-ounce copper rounds in various designs, one-pound copper bars, and novelty copper coins.

Unlike gold and silver bullion, copper products are not purchased as serious financial investments due to the metal's low per-ounce value and the high premiums charged relative to melt value. A one-ounce copper round that costs $1-3 at retail contains only $0.25-0.35 worth of copper at spot price, representing a premium of 300-800% over melt value.

Copper has a long history in the numismatic world. Pre-1982 U.S. pennies are 95% copper and contain approximately 2.95 grams of copper each, making them worth more than their face value when copper prices are high. Some collectors specifically save pre-1982 pennies for their copper content.

The conversion from per-pound to per-ounce pricing is straightforward: divide the COMEX per-pound price by 14.5833 (the number of troy ounces in one avoirdupois pound). This conversion allows copper enthusiasts to compare their holdings directly against gold, silver, platinum, and palladium using the same unit of measurement that dominates precious metals markets.

Standard quote: Copper spot is quoted per pound on COMEX (symbol HG)
Troy ounce conversion: 1 troy ounce = 31.1035 grams = 0.0686 pounds
Price level: Copper trades in cents per troy ounce, far cheaper than precious metals
Bullion products: Copper bars and rounds are popular collectible and stacking products
Demand drivers: Electrical wiring, construction, and EV manufacturing drive copper pricing

Where to Buy Copper

Frequently Asked Questions

How much is copper per troy ounce?
Multiply the COMEX per-pound price by 0.0686 (since 1 troy ounce = 31.1035g and 1 pound = 453.592g). For example, if copper is $4.50 per pound, one troy ounce costs approximately $0.31. Check the live chart above for the real-time copper price per troy ounce.
Why is copper quoted per pound instead of per ounce?
Copper is an industrial base metal traded in large volumes, not a precious metal. Each COMEX copper futures contract represents 25,000 pounds. Per-pound pricing keeps the numbers practical for industrial buyers. Precious metals like gold and silver use troy ounces because they trade in much smaller quantities at much higher prices per unit weight.
Is buying copper by the ounce worth it?
Copper bullion bars and rounds are more of a collectible or novelty item than a financial investment. Copper is so cheap per ounce compared to gold or silver that the premium over spot price on small copper products runs 50-200%. Investors looking for meaningful copper exposure typically buy larger bars (1 lb, 5 lb, or 10 lb) to minimize the per-ounce premium, or invest through futures and ETFs.
How does copper per ounce compare to silver?
Silver is roughly 80 to 100 times more expensive per troy ounce than copper. For example, if silver is $30 per troy ounce and copper is $0.31 per troy ounce, the silver-to-copper ratio is about 97:1. This massive price difference is why copper is classified as a base metal rather than a precious metal, despite its critical importance in industry and the global economy.
