Enter the total cost of the silver and the total weight of the silver into the calculator to determine the cost per gram of silver.

Cost Per Gram of Silver Formula

The following equation is used to calculate the Cost Per Gram of Silver.

CPGS = TCS / TWS
  • Where CPGS is the cost per gram of silver ($/gram)
  • TCS is the total cost of the silver ($)
  • TWS is the total weight of silver (grams)

To calculate the cost per gram of silver, simply divide the total cost of the silver by its weight in grams. Use the unit converter to the side to switch between units of weight.

What is the Cost Per Gram of Silver?

The cost per gram of silver is calculated from the spot price. To calculate the cost per gram, you would divide the spot price by 31.1035 for silver. A troy ounce contains 31.1035 grams, so this formula will convert the spot price into an ounce and then divide it into its weight in grams.

CPGS = SPO / 31.1035

  • Where CPGS is the cost per gram of silver
  • SPO is the spot price per ounce

The cost per gram of silver is about one-tenth the price of gold. For example, as of February 2020 , the spot price for an ounce of gold was $1,841.00 per ounce.

The spot price for silver was $23.79 per ounce. This means that the cost per gram of silver and the cost per gram of gold are about 1/10th each other.
