How much does air weigh?

Although we may not notice it, we support an invisible column of air weighing almost a ton on our shoulders . What happens is that the air pressure is exerted in all directions , which explains why it does not crush us. In addition, the air bar that we carry is balanced by the internal pressure of the body. This prevents us from wrinkling as if we were a soda can that had been evacuated.

The mean value of atmospheric pressure at sea level is approximately 1 kg / cm2, which means that for every square centimeter of surface area a pressure of one kilogram is exerted. However, the mean value of the pressure varies with height, so that it is lower the higher we are. Thus, at the top of Everest it reaches a value of only 0.316 kg / cm2.
