Answer 3

The ounce is the name for a number of different units of mass (oz), and also of two units of fluid volume (fl oz) and of one unit of force, the ounce-force (ozf). See Imperial system of units and U.S. customary units for more about the frameworks within which these units are defined.

avoirdupois ounce defined by the avoirdupois system of mass (see pound (mass)). There are 16 ounces in the avoirdupois pound. The avoirdupois ounce is approximately 28.35 gram (or 437.50 grains).
troy ounce defined by the troy system of mass. In troy weight, there are 12 ounces in a troy pound, and a troy pound is 5760 grains (about 373.24 g), rather than the 7000 grains (about 453.59 g) in the avoirdupois pound. Note: at roughly 31.104 g (or 480 grains), the troy ounce is about 10 per cent more than the more common avoirdupois ounce of 28.35 g (or 437.50 grains). There are approximately 14.5833 troy ounces in an avoirdupois pound. These troy ounces are now used only when weighing precious metals like gold, platinum and silver. One ounce of gold is always 31.1 g. "Maria Theresa ounce" was once introduced in Ethiopia and some European countries, which was equal to 31.1025 g.

Hope you got the exact definition.
