OK, so 1 kg = 1 litre, so 0.1 kg = 0.1 litre
0.1 litre = 3.38 ounces, but that is a fluid measurement.
if it were dry weight, then 1kg = 3.5274 ounces
I thought 1 kg was equal to about 2.2 pounds ?
having a litre be both a liquids and dry unit is tough. Probably why
us Americans have such a hard time with SI units. Having a litre be
two different types of measures, dry volume and liquid but having the
same name for each makes it hard to know what we are doing.
I mean how many ounces would it be and is that dry ounces or liquid
ounces ?
I think one reason the transistion is because of the few things that
cross between volumes and weights.
Regardless, if the main ingredient is silver, then the cost will be
PDH.
and personally, I feel sorry for the bloke who has to convert the
troy weight of silver to ounces to litres to kg ! No wonder the cost
is so high !

(not sure if it is liter or litre ? )
