[QUOTE="dmonwaxa, post: 25777, member: 927"] 31 g in 1 Troy oz 20 dwt in 1 Troy oz #g in 1dwt = 31/20 1dwt = 1.55g wax weight in g x spg or density (of alloy being used) gives you the amount needed for casting. ex: wax weight = 1.63 g sp/density = 14.2 metal needed = 1.63 x 14.2 metal needed = 23.14 gm from ex above dwt = 1.63g/1.55g= 1.05dwt metal needed 1.05dwt = ?g metal = dwt x sg x g/dwt = 1.05 x 14.2 x 1.55 = 23.14g measuring in dwt is antiquated you'll be working backwards converting g to dwt and back again, just use g (gm/grams) that way you dont have to worry about grains etc. Much simpler and more accurate. Its science use scientific units of measurements. [/QUOTE]
