The avoirdupois ounce (oz) equals exactly 28.349523125 grams or 1/16 of an avoirdupois pound. It is widely used in the US and UK for food portions, product packaging, and everyday measurements. Note that the troy ounce (31.1035 g), used for precious metals like gold and silver, is a different and heavier unit than the avoirdupois ounce.
The US short ton (commonly just "ton" in American usage) equals exactly 2,000 avoirdupois pounds or approximately 907.18474 kilograms. It is the standard bulk commodity unit for coal, steel, cement, and freight in the United States. The "short" qualifier distinguishes it from the UK long ton (2,240 lb) and metric ton (1,000 kg).
The word "ounce" derives from Latin uncia (a twelfth), originally 1/12 of the Roman pound. The avoirdupois ounce developed in medieval England specifically for the wool trade, creating a 16-ounce pound distinct from the Troy 12-ounce pound. The British Imperial system codified the ounce in 1824. The modern exact definition (28.349523125 g) was set by the 1959 International Yard and Pound Agreement.
Interesting fact: A troy ounce (31.1 g) used for gold is heavier than an avoirdupois ounce (28.35 g) used for food — so an "ounce" of gold contains more metal than an "ounce" of flour. A standard large hen's egg weighs approximately 56–63 grams (about 2 oz).
The short ton emerged in the United States as commerce adopted 2,000 pounds as a round-number bulk standard, diverging from the British 2,240-lb long ton. It was codified in the US Customary system in the 19th century. US coal production, steel output, and grain yields are still reported in short tons domestically, though international trade uses metric tons. The US is one of only three countries (with Myanmar and Liberia) not officially on the metric system.
Interesting fact: A fully loaded standard US freight car carries approximately 100 short tons of cargo. The US historically produced ~1 billion short tons of coal per year; modern US coal consumption has fallen to about 400–500 million short tons annually.
