Ounce (oz)
Definition: An ounce (symbol: oz) is a unit of mass in the imperial and US customary systems. One ounce is equal to 1/16 of a pound or approximately 28.3495 grams.
History/origin: The ounce originated from the Roman uncia, which was 1/12 of a Roman pound. Over time, different regions had various definitions of the ounce, but the avoirdupois ounce became widely used in the 14th century. The modern definition was established in 1959.
Current use: Primarily used in the United States for measuring packaged foods, cooking ingredients, and postal items.
Kilogram (kg)
Definition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It is currently defined based on the fixed numerical value of the Planck constant.
History/origin: The kilogram was introduced during the French Revolution in 1795 as part of the metric system. Initially defined as the mass of one liter of water at its freezing point, it was later refined for greater precision. In 1875, the Treaty of the Meter established the International Bureau of Weights and Measures (BIPM) to standardize measurements, including the kilogram. The definition of the kilogram was updated in 2019 to be based on the Planck constant rather than a physical object.
Current use: As a base unit of SI, the kilogram is used globally in nearly all fields and applications, with some exceptions in countries like the United States.
