Understanding Kilograms and Pounds: The Basics
The Metric System and Kilograms
The kilogram (kg) is the base unit of mass in the International System of Units (SI), which is the standard measurement system used worldwide in scientific, industrial, and everyday contexts. The kilogram is defined by the Planck constant, making it a precise and stable unit. It is widely used in countries that adopt the metric system, including most of the world, for measuring body weight, food, machinery, and more.
The Imperial System and Pounds
The pound (lb) is a unit of weight used primarily in the United States, the United Kingdom, and some other countries that use the Imperial or US customary measurement systems. The pound has historical roots dating back to medieval England, originally derived from the Tower pound. Today, the pound is standardized in the US and Britain as exactly 0.45359237 kilograms.
