Facts about the Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI). Defined originally as the mass of a liter of water, it was later represented by a platinum-iridium prototype kept in France. In 2019, it was redefined using Planck's constant, linking mass to a fundamental constant of nature. Kilograms are widely used for weighing groceries, people, and cargo worldwide.

The ounce (oz) is a unit of mass used mostly in the U.S. and U.K. One ounce is equal to approximately 28.3495 grams. Ounces are used for measuring food, precious metals, and smaller consumer goods. In cooking and nutrition, ounces appear frequently on ingredient labels and packaging.
