What is true about barometric and atmospheric pressures?

Barometric pressure and atmospheric pressure are terms that are often used interchangeably, as they refer to the pressure exerted by the weight of the atmosphere. Atmospheric pressure changes with altitude and weather conditions but is generally represented by the barometric pressure measured by a barometer. On a given day at a specific location, barometric pressure directly reflects atmospheric pressure, making them equivalent in that context.

It’s important to note that while they can vary, especially when you consider different geographic locations or altitudes, the fundamental concept is that barometric pressure is a measure of atmospheric pressure at a specific point in time and space. Therefore, they are not always equal in terms of their values at different locations or times but are fundamentally describing the same physical phenomenon.
