Kilogram
The kilogram or kilogramme (symbol: kg ) is the base unit of mass in the International System of Units (SI). Until 20 May 2019, it remains defined by a platinum alloy cylinder, the International Prototype Kilogram (informally Le Grand K or IPK), manufactured in 1889, and carefully stored in Saint-Cloud , a suburb of Paris . After 20 May, it will be defined in terms of fundamental physical constants .

The kilogram or kilogramme (SI unit symbol: kg ) is the base unit of mass in the International System of Units (SI), and is defined as being equal to the mass of the International Prototype of the Kilogram ( IPK , also known as "Le Grand K" or "Big K"), [2] a cylinder of platinum-iridium alloy stored by the International Bureau of Weights and Measures at Saint-Cloud , France. It is the only metric base unit which is defined by an artifact. |

The kilogram or kilogramme (SI unit symbol: kg ; SI dimension symbol: M), is the base unit of mass in the International System of Units (SI) (the Metric system ) and is defined as being equal to the mass of the International Prototype of the Kilogram ( IPK ). [2] The avoirdupois (or international ) pound , used in both the Imperial system and U.S. customary units , is defined as exactly 0.45359237 kg , making one kilogram approximately equal to 2.2046 avoirdupois pounds. Other traditional units of weight and mass around the world are also defined in terms of the kilogram, making the IPK the primary standard for virtually all units of mass on Earth. |

The kilogram is defined as being equal to the mass of the International Prototype Kilogram [1] ( IPK ), [Note 3] which is almost exactly equal to the mass of one liter of water. It is the only SI base unit with an SI prefix as part of its name. It is also the only SI unit that is still defined by an artifact rather than a fundamental physical property that can be reproduced in different laboratories. |
