How to calculate the cobalt to rhodium ratio
Cobalt to Rhodium ratio = Cobalt price per Metric Ton ÷ Rhodium price per Troy Ounce
The two legs use different units, so the result is a rate — Troy Ounces of rhodium per Metric Ton of cobalt — rather than a plain count.
Worked example, live prices: $56,290.00 ÷ $8,800.00 = 6.397. The inverse is 0.1563.
