The ounce comes from the Roman uncia, meaning one twelfth. Confusingly it is now one sixteenth of a pound rather than one twelfth, a change that followed the shift from the Roman to the avoirdupois system. It is used for food portions, packaging weights and postal rates in the United States, and for precious metals in a different form โ the troy ounce, which is heavier and used only for gold, silver and platinum. A slice of bread weighs about 1 ounce, and a standard tin of soup is around 10.75 oz.
Worked through with real numbers: 1 oz is 28.35 g, 5 oz is 141.748 g, 50 oz is 1417.476 g.
As for the other side of the conversion: A standard paperclip weighs about 1 gram, and a metric cup of flour is roughly 125 g.
Strictly these are conversions of mass rather than weight โ mass is how much matter something contains, weight is the force gravity exerts on it. The distinction rarely matters on Earth, where the two are proportional, but it is why the same object masses the same on the Moon while weighing about a sixth as much.
