Abstract
The invention is a method of measuring an apparent weight of a substance, while concurrently measuring a surface temperature of the substance and an ambient air temperature surrounding the substance, then predicting buoyancy forces acting upon the substance based on these temperature measurements. Thereafter, the true weight of the substance can be determined by correcting the apparent weight by the predicted buoyancy forces acting upon the substance.
