About Ounces
The avoirdupois ounce (oz) is 1/16 of a pound, equal to approximately 28.35 grams. It is the everyday ounce used in the United States and United Kingdom for food portions, household quantities, and general trade. US food packages, recipe measurements, and nutrition labels reference ounces; a standard stick of butter is 4 oz, a can of soup typically 10.75 oz, and a baseball weighs 5-5.25 oz. Unlike the troy ounce (31.10 g) used for precious metals, the avoirdupois ounce (28.35 g) is lighter.
About Grams
The gram (g) is the basic metric unit of mass, equal to one thousandth of a kilogram. It is universally used in cooking, nutrition, postal services, and scientific measurement. Almost all food packaging worldwide shows nutritional information per 100 g. A US nickel coin weighs exactly 5 g, a teaspoon of sugar about 4 g, and a standard paperclip approximately 1 g. In chemistry, the gram is central to molar mass: one mole of carbon-12 atoms weighs exactly 12 g. Postal rates are typically scaled per gram or per 100 g.
