Kilogram
A kilogram is the SI base unit of mass, with the symbol kg. It is the standard unit used in science, schools, and most countries for everyday weighing.
The word comes from French “kilogramme”, first used in the late 1700s. Since 2019, the kilogram has been defined using the Planck constant, which makes it stable and precise worldwide.
- Body weight in many countries
- Grocery items like rice, fruit, and meat
- Shipping and parcel weights
- Gym weights and equipment
- Science labs and classrooms
Ounce
An ounce is a unit of mass, with the symbol oz. On most weight labels, “ounce” means the avoirdupois ounce used in the US and UK weight systems.
The ounce name comes from the Latin “uncia”, meaning one twelfth. The modern international avoirdupois ounce is defined as exactly 1/16 of a pound, which equals exactly 28.349523125 grams.
- Nutrition labels and portion sizes
- Cooking and baking in US recipes
- Small package and product weights
