Worth knowing. An ounce of gold and an ounce of flour are not the same weight — gold is sold in troy ounces, which are about 10% heavier. Both are in the table.

What each unit actually is

Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
