Water's mass depends on its purity. The old definition of a gram was the mass of one ml of pure water at 0 degrees C.
The mass of a column of water is therefore approximately one gram per ml, where the number of ml is the column's length in cm, times 2pi times its radius in cm squared.
Now, weight is proportional to mass and the inverse square of the distance between two bodies. One body is the column of water and we'll assume the other to be the earth. Assume this column of water is "close" to the earth and a good estimate for the weight is 9.81 times the water's mass.
On the earth's surface, at 0 deg C, a column of pure water's mass, in grams, is approximately 9.81*L*2pi*r2 with L and r in cm.
A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
An air column is a vertical or elongated volume of air with specific physical properties, such as temperature, pressure, and density, that can affect the movement of sound waves or weather patterns. It is frequently studied in physics and meteorology to understand how air behaves in different conditions.

a rotating column of air that extends from a thunderstorm to the ground is a Tornado
A spinning column of air is known as a vortex or a whirlwind. It can vary in size and intensity, ranging from dust devils and waterspouts to tornadoes and hurricanes. The spinning motion is caused by variations in air pressure and temperature.
Trajan's Column is estimated to weigh around 1,110 tons.
25 pounds

a little
If you're weighing it at sea level, then it weighs roughly 14.6 pounds for every square inch of area that the bottom of the column rests on.
Air is relatively light so if your column does not have a large cross section or a great height maybe grams would be a good choice. The column of air above a one square meter area at sea level that extends to the top of the atmosphere should probably use the unit kilograms.
depends on how much air in tires
A lot
i believe 9.00
Mac book air weight is 2.3pound (1.06kg)
The Nelson's Column weighs approximately 160 tons.
Air conditioners vary in weight. Some air conditioners can weigh more than a ton, while others only 50 to 60 pounds.
