Examples

If you have 5.0 grams of 14KT scrap and gold is $1700.00 today, then $1700.00 divided by 31.1 equals $54.6623 multiplied by .5833 (14KT) equals $31.88 per gram. $31.88 multiplied by 5.0 grams equals $159.40. Now let's say you have 15.3 grams of 10KT gold scrap. $1700.00 divided by 31.1 equals $54.6623 multiplied by .4167 (10KT) equals $22.78 per gram. $22.78 multiplied by 15.3 grams equals $348.53.
