Conversion Factors - (MINFILE Coding Manual) 
| 1 ounce (troy) |
= 31.1034768 grams. |
| 1 troy ounce per short ton |
= 34.2857 grams per metric tonne |
= 34.2857 ppm |
| 1 gram per metric tonne |
= 0.0292 troy ounce per short ton |
| 1 kilogram (kg) |
= 32.151 ounces (troy) |
35.274 ounces (avdp) |
2.205 pounds (avdp) |
| 1 ounce (avdp) |
= 28.3495 grams |
| i.e. 1 troy ounce = 31.103481 grams but a troy ounce/ton using a conversion of 31.103481 gives you only GRAMS PER SHORT TON. To complete the metric conversion you must also convert short tons to tonnes using the conversion factor 0.9071. So: 31.103481 grams per ton 0.9071 = 34.2857 grams per tonne. |
