Iridium Price per Kilogram: Conversion Table#

| Weight | Grams | Troy ounces | Price (USD) |
|---|---|---|---|
| 1 gram | 1 | 0.0321507466 | $262.03 |
| 1 troy ounce | 31.1034768 | 1 | $8,150.00 |
| 1 kilogram | 1,000 | 32.1507466 | $262,028.58 |
How the Kilogram Price Is Calculated#
The USD price per kilogram is the Johnson Matthey Base Price for iridium sponge, per troy ounce, divided by 31.1034768 and multiplied by 1,000.
Price per kilogram (USD)
= (Johnson Matthey Base Price per troy ounce, USD / 31.1034768)
x 1,000
Illustrative only (not today's price): if the Johnson Matthey Base Price = $X/troy oz, then
price per kilogram = (X / 31.1034768) x 1,000
That divides the ounce-based Base Price by the exact grams in a troy ounce, then scales it to a kilogram. A separate Umicore quote, in euros per gram, needs the same-day EUR/USD rate before converting to USD.
What Moves the Iridium Price#
Three factors move the iridium price: the Base Price, dealer and refiner premiums, and industrial demand. The fuller picture lives on iridium price today, and what drives the platinum price covers all nine factors across every PGM.
- The Base Price, reset four times a business day in Hong Kong, London and New York.
- Dealer and refiner premiums, wider for sponge and small lots.
- Industrial demand from electrolyzer and catalyst manufacturers.
How Iridium Is Traded by the Kilogram#
Iridium has no exchange, no futures contract and no bullion coin or bar product at the kilogram weight: the published number is the Johnson Matthey Base Price for sponge, or a comparable named quote from Heraeus or Umicore, never a spot price or a benchmark. The table below keeps the two named series and their units and currencies separate, since neither is interchangeable with the other.
| Series | Quote type | Unit as published | Currency | Frequency | Source |
|---|---|---|---|---|---|
| Johnson Matthey Base Price | Refiner base price (sponge) | Troy ounce | USD | 4x per business day | Johnson Matthey |
| Umicore PMM quote | Dealer quote | Gram | EUR | Daily | Umicore |
- Refiner weight account: metal held in a named refiner's account, drawn down against the Base Price.
- Phone or email desk: a negotiated quote for a one-off lot, at a premium.
Iridium has neither an LPPM Good Delivery bar list nor a sponge accreditation scheme, unlike platinum, palladium and rhodium. Buyers and sellers typically work through investing in iridium or a refiner's request-for-quote desk, not a retail dealer.
Iridium vs Gold, per Kilogram#
Per kilogram, iridium and gold sit on separate USD benchmarks; the ratio moves daily, not by a fixed multiple. Iridium tracks the Base Price, gold the LBMA Gold Price auction (IBA), so the two can move in opposite directions. A dedicated comparison page is not yet live.
