The amount of gold found in ore is often measured in parts per million, but a ton of mined ore yields so little gold that the amount mined is usually measured in grams. While it's easier to weigh the mined gold in grams, the price of gold is commonly provided in dollars per ounce. It's important to know how to convert the grams of gold found in each ton of mined ore into the equivalent ounces of gold in that same ton. The amount of grams of gold contained in an ounce is 31.1034768 grams per ounce, making the conversion from grams to ounces is a simple math equation.
Things You'll Need
- Assayer's report
Read the assayer's report on a sample taken from a ton of ore and find the number of grams of gold contained in the sample. Enter this number into the calculator.
Press the division symbol and enter 31.1034768. Press equals.
Note the result. This the exact number of troy ounces of gold contained in the ton of ore. For example, a ton of ore containing 40 grams of gold equals 1.286 ounces of gold in that ton. Forty divided by 31.1034768 equals 1.286.
