Excerpt: The kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI, from the French, which is the modern standard governing the metric system. The kilogram is defined as being equal to the mass of the International Prototype Kilogram (IPK), which is almost exactly equal to the mass of one liter of water. The avoirdupois (or international pound, used in both the Imperial system and U.S. customary units, is defined as exactly 927 kg, making one kilogram approximately equal to 2.2046 avoirdupois pounds. In everyday usage, the mass of an object given in kilograms is often referred to as its weight, which is the measure of the gravitational force-or heaviness-of an object. Weight given in kilograms is technically the non SI unit of measure known as the kilogram-force. The equivalent unit of force in the avoirdupois system of measurement is the pound-force.
