Think i get it now in the drill results they have opt and gpt the troy opt are for a ton and the gpt are for a tonne ( 1 ton = 0.907 tonnes) so as we are working in meters not feet and inches i will divide the grams in the results by 31.1034768 to get the total troy oz in a tonne.

so the results for Kodiak Drills 2.9 m Grading 203 gpt (5.92 opt) Gold / Expands Magnitude of Golden Mile Discovery

would be 2.9 m Grading 203 gpt (6.53 opt) using a tonne for both
