Kilograms

📖 A kilogram is a metric unit of mass that is equal to 1000 grams or approximately the weight of a liter of water. It is commonly used to measure the weight of people, animals, and large objects.

💡 The kilogram is the only SI base unit that is still defined by a physical artifact, a platinum-iridium cylinder called the International Prototype of the Kilogram. However, this definition is set to change in 2019 with the redefinition of the kilogram based on fundamental constants.
