Air Density and Buoyancy Correction

Abstract

Two weights (standards of mass) are compared usually in air. Upward buoyancy forces act on each weight separately; the values of these upward forces are proportional to the product of the respective volumes of the two weights and air density at the time of comparison. Weights of same nominal value have different volumes if their density is not equal. Volume of a stainless steel 1-kg weight differs from that of the platinum iridium mass standard by about 85 cm3.
