Kilograms to Pounds

Convert kilograms to pounds. The same mass as a cubic decimeter of water was the original definition of a kilogram. Later it was determined that the kilogram is defined as the International Prototype Kilogram. It is very close to the mass of one liter of water. The International Prototype Kilogram is an human artifact and its mass is not constant. Pounds is often confused with mass. As a result, many are still confused as to the difference between force (weight) and mass. A person weighing 100 pounds on earth would only weigh 16 pounds on the moon - however, their mass would remain the same.
