While the pressure that the air exerts over the surface of the earth is approximately 14.7 pounds per square inch, most pressure gauges will read ‘0’ psi when open to the atmosphere. This is because pressure gauges measure a “relative pressure” compared to the surrounding atmospheric pressure. When a gauge is put on a tire […]

Because the air that fills our atmosphere has a weight, it also exerts pressure over the surface of the Earth. This pressure is referred to as “atmospheric pressure”, “air pressure”, or “barometric pressure”. At sea level, experiments have proven that the atmospheric pressure is 14.696 psi. Since the density of air decreases as the elevation […]

Pressure is the measurement of a force applied over an area. The equation to calculate pressure is Pressure equals Force divided by Area. Imagine that a 200-pound man stood on top of a table that has a 10 square foot area. Assuming the man’s weight could be evenly distributed across the table, the pressure exerted […]
