Abstract
The most accurate value of air density is obtained by a calculation based on the equation using measured atmospheric parameters approved by the International Committee for Weights and Measures in 1981. When a 1-kg steel weight was calibrated against the prototype kilogram using the international expression for determining the density of air, experimental results showed that the estimated uncertainty of the air density was 1.45x10-4 mg.cm-3 and the uncertainty of air buoyancy was 11.3 mg.
