Ounces
One ounce is a unit of mass/weight equal to 1/16 of a pound. The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.[1]
The ounce is a US customary and imperial unit of weight. Ounces can be abbreviated as oz, for example 1 ounce can be written as 1 oz.
Kilograms
The definition of the kilogram changed in 2019. Previously, one kilogram was equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.
The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[2] It is roughly equal to the mass of 1,000 cubic centimeters of water.
The kilogram, or kilogramme, is the SI base unit for weight, and is also a multiple of the gram. In the metric system, "kilo" is the prefix for 103. Kilograms can be abbreviated as kg, for example 1 kilogram can be written as 1 kg.
