Since 1889, the kilogram has been defined as the mass of an object. The international prototype kilogram is a platinum alloy machined into a right-circular cylinder with a height and diameter of 3.917 centimeters.As the only remaining unit of metric measurement still tied to a physical artifact, the international prototype for the kilogram and its many copies, currently stored in different countries worldwide, remain unreliable means to standardize and control the measurement of weight. Andrés Ramírez Gaviria’s ongoing series presents an image of this international prototype kilogram and certain official copies.
