Question

How do you calculate barometric pressure?

Answer 1

You don't calculate it. It's just there. like temperature is just there.

Answer 2

You need not calculate it;if you just know how to read a barometer which automatically measures the atmospheric pressure,that is enough. You get the value.

On the other hand,if the place where the barometer is kept is situated at a higher elvation and if you want to reduce the value to the mean sea level(ie, calculating what would be the pressure if the place were to be at sea level, for comparison purposes),then you have to calculate it using a formula.

Answer 3

I'm not sure I understand your question.  Barometric pressure is measured by a barometer.

You may have to convert between mm Hg, in Hg, of KPa (the three units commonly used to express barometric pressure).

Answer 4

You don't calculate it. You have to look at a barometer (an instrument that measures air pressure) and it'll tell you the air pressure.

Answer 5

slide a rhinocerous up your shoe and see what happens
