Unit Information & History
Kilogram
Definition: The base unit of mass in the International System of Units (SI). Originally defined by the mass of a liter of water.
History: For over a century, it was defined by a physical platinum-iridium cylinder kept in France. In 2019, it was redefined based on the Planck constant, making it based on fundamental physics rather than a physical artifact.
Current Use: The standard unit for mass worldwide in science, commerce, and daily life (except in the US).
Pound
Definition: A unit of mass in the imperial and US customary systems, defined as exactly 0.45359237 kilograms.
History: Descended from the Roman libra (hence the abbreviation "lb"). Throughout history, many different "pounds" existed for different goods. The "avoirdupois pound" is the standard used today.
Current Use: Standard unit of weight in the United States and still commonly used in the UK for body weight.
Ounce
Definition: A unit of mass equal to 1/16 of a pound or approximately 28.35 grams.
History: Like the pound, it derives from Roman units. The "uncia" was 1/12 of a libra, but the modern avoirdupois ounce is 1/16 of a pound to align with the 16-ounce pound standard.
Current Use: Used in the US and UK for measuring small weights, especially in cooking (ingredients) and postage.
