Converting oz. to grams ?
Sorry if this seems to be a dumb question but I am curious. When converting oz to grams ( I find it easiest in grams with my scale) would you round up? I am not a math whiz so I cheat and look it up. For instance 1 oz = 28.3495g would you leave this at 28 grams? Say it was 28.687 would you round that up to 29 grams? Or should I buy a more precise scale?
