That's a very vague question.
Gold is typically measured in Troy ounces, not pounds or tons. Also, if it's verbal, is it a ton or tonne? Long ton, metric ton, etc.
Is there such a thing as a Troy ton? If not, how/when do you convert? FWIW, there's not 16 ounces in a Troy pound. 20?
IIRC, there's abit over 7 Troy ounces/avoir dupois (sp?) pound.
You have the potential to impress the interviewer, then again, you can make yourself look like an ass (like I likely did ).
