Introduction to Kilograms and Pounds

The Metric System and Kilograms

The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is widely used globally, especially in countries that follow the metric system. The kilogram was originally defined in 1889 as the mass of a platinum-iridium alloy cylinder stored in France, known as the International Prototype Kilogram. Today, it is defined based on fundamental constants, ensuring high precision.

The Imperial System and Pounds

The pound (lb) is a unit of weight commonly used in the United States and some other countries that follow the imperial or customary systems. The pound has various definitions historically, but the most widely recognized is the avoirdupois pound, which is used in most contexts today. One pound equals 16 ounces.
