Dear Predrag,
Q: Which is heavier -- an ounce of gold or an ounce of lead? A: An ounce of gold.
Q: Which is heavier -- a pound of gold or a pound of lead? A: An pound of lead.
Explanation: 1 Gold is measured in Troy ounces (1 Troy ounce = 31.1035 grams) and lead is measured in Avoirdupois ounces (1 Avoirdupois ounce = 28.349 523 grams). So an ounce of gold is heavier than an ounce of lead. 2 There are 12 Troy ounces in a Troy pound (1 Troy pound = 373.242 grams), but there are 16 Avoirdupois ounces in an Avoirdupois pound (1 Avoirdupois pound = 453.592 37 grams). So a pound of lead is heavier than a pound of gold.
And don't forget to differentiate between dry ounces, that measure mass, and fluid ounces, that measure volume.

I have been using this site http://www.sciencemadesimple.net/EASYweight.html to convert grams -ounces etc but was surprised when I had a choice between troy or avoirdupois ounces. What the heck is this? Like one is not complicated enough. It turns out that products that I am importing from europe are using avoirdupois conversio.
Thanks, Predrag
