subtract 0.0011 from the density in vac to get density in air.
Air density - at least, the average air density - pretty much depends on the altitude. I suggest you look up the altitude of both places (you can probably find it on the corresponding Wikipedia articles); the place with the lower altitude should have a greater air density.
Air density determines how much mass is present in a given volume of air. It affects things like buoyancy, pressure, and the ability of objects to move through the air, such as airplanes and birds. Changes in air density can impact weather patterns and climate.
The density of heated air is less than the density of cooler air.
The density of a substance stays the same, no matter how much space it takes up.
Density of air is a measure of how much mass is contained in a given volume of air. It is typically expressed in units such as kilograms per cubic meter or grams per cubic centimeter. Air density can vary based on factors such as temperature, pressure, and humidity.
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
Air has both density and pressure.
When air is compressed to half its volume, its density doubles. This is because the same mass of air is now occupying half the volume, resulting in a higher concentration of air molecules in that space.
Pressure affects the density of air by increase of pressure increases the density

An air bubble clinging to a metal object would decrease the overall density of the object. The presence of the air bubble adds volume without contributing much mass, leading to a lower density calculation.
