Kilograms (kg) to Ounces (oz) Conversion
Kilograms
The kilogram is the SI base unit of mass. From 1889 to 2019, it was defined by the International Prototype of the Kilogram — a physical cylinder of platinum-iridium alloy stored near Paris. In 2019, the kilogram was redefined in terms of Planck's constant (h = 6.62607015 × 10⁻³⁴ J·s), making it the first base unit defined entirely by a fundamental constant of nature. This eliminated the risk of the kilogram gradually changing mass due to contamination of the physical prototype.
Ounces
The ounce (avoirdupois) is a unit of mass equal to exactly 28.349523125 grams, or one sixteenth of a pound, used in the United States and United Kingdom for food portions, postal weights, and product labelling. It must be distinguished from the troy ounce (31.1035 g), used exclusively for precious metals, and from the fluid ounce, which is a unit of volume.
