Appendix VII - Conversion Factors

 

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.
