Air Density and Buoyancy Correction,tainty of 1 in ., we must be able to evaluate buoyancy correction with an uncertainty of 1 part in .. This means that volume of the weight under test must be measured or known with the uncertainty of not worse than 1 in . and the density of air should also be measured with the uncertainty of not worse than 1 in ..
