2. The History and Significance of Kilograms and Pounds

Understanding the historical context of these units helps appreciate their significance. At HOW.EDU.VN, our experts delve into the origins and evolution of both kilograms and pounds, providing a comprehensive perspective.

2.1. The Kilogram: A Metric Standard

The kilogram is the base unit of mass in the International System of Units (SI). It was initially defined in the late 18th century as the mass of one liter of water. The kilogram is part of the metric system, which is used by most countries worldwide.

History of the Kilogram:

1795: The kilogram was first defined by the French as the mass of one liter of water at the temperature of melting ice.
1799: A platinum cylinder was created to represent the kilogram.
1889: The International Prototype Kilogram (IPK), a platinum-iridium cylinder, was adopted as the standard.
2019: The kilogram was redefined based on fundamental physical constants, specifically the Planck constant, ensuring greater stability and accuracy. According to a study by the National Institute of Standards and Technology (NIST) in 2019, this redefinition has significantly improved the consistency of mass measurements across different laboratories.

2.2. The Pound: An Imperial Measurement

The pound is a unit of mass in the imperial and United States customary systems of measurement. There are different definitions of the pound, but the most common is the international avoirdupois pound, which is defined as exactly 0.45359237 kilograms.

History of the Pound:

Ancient Rome: The term “pound” comes from the Roman term “libra pondo,” meaning “a pound weight.”
Middle Ages: Various definitions of the pound existed in different parts of Europe.
1959: The international avoirdupois pound was defined, standardizing the unit.

2.3. Why Two Systems?

The coexistence of these two systems stems from historical and political reasons. The metric system was developed during the French Revolution and promoted as a universal, rational system. However, countries like the United States and the United Kingdom, with strong historical ties to their own measurement systems, were reluctant to switch entirely.

Today, most countries use the metric system for most purposes, but the pound remains in use in the United States for everyday measurements like body weight and certain types of commerce.
