Kilogram
Definition: The kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It is defined by taking the fixed numerical value of the Planck constant.
History/origin: For over 100 years, the kilogram was defined by a physical object called the "International Prototype of the Kilogram" (IPK), before being redefined by physics in 2019.
Current use: It is the most common unit for measuring weight globally, used for everything from human body weight and groceries to industrial shipping.
Pound
Definition: The pound (symbol: lb) is a unit of mass used in the imperial and US customary systems. The international avoirdupois pound is defined as exactly 0.45359237 kilograms.
History/origin: The pound was derived from the Roman "libra." Over centuries, many different versions of the pound existed until the international pound was agreed upon in 1959.
Current use: The pound is the primary unit of body weight and grocery weight in the United States, and is also common in the United Kingdom and Canada.

Did You Know?
- Did you know? Until 2019, the Kilogram was defined by a physical platinum-iridium cylinder kept in a vault in France. Now, it is defined by a constant of nature called the Planck constant!
- The abbreviation for pound, "lb," comes from the Roman unit of weight, the "libra." This is also why the astrological sign Libra is represented by a set of scales.
