The Basics of Kilograms and Pounds
What is a Kilogram?
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It was originally defined in 1795 as the mass of a liter of water but has since been redefined based on fundamental constants. Today, the kilogram is defined in terms of the Planck constant, making it a precise and universal measure.
Kilograms are commonly used in most countries around the world for everyday weight measurements, including body weight, produce, and industrial measurements.
What is a Pound?
The pound (lb) is a unit of weight that originated from the Roman "libra," which was a unit of mass used in ancient Rome. The pound is still used primarily in the United States, the United Kingdom, and some other countries for measuring body weight, food, and other commodities.
The pound is further subdivided into ounces, with 16 ounces making up one pound.
