About the ounce and the gram

The ounce

The avoirdupois ounce (oz) is a unit of mass in the imperial and US customary systems, defined as exactly 28.349523125 grams (1/16 of an avoirdupois pound). It is the standard small-mass unit in the United States for food packaging, recipes, and postal weights. Do not confuse it with the troy ounce (used for precious metals, 31.1035 g) or the fluid ounce (a volume).

The gram

The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.
