About Pound (lbs)

Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. One pound is exactly 0.4535 kilograms.

History: The pound originates from the Roman unit “libra,” which is where the abbreviation “lb” comes from. Various definitions of the pound existed throughout history, but in 1959, the international avoirdupois pound was standardized as exactly 0.4535 kilograms. The avoirdupois system, widely used since the 13th century, divides the pound into 16 ounces, making it convenient for trade and commerce.

Current use: Widely used in the United States and the United Kingdom for everyday measurements, particularly body weight, and in food labeling.

About 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: 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.
