## What is the standard atmospheric pressure in mm Hg What is it in kPa?

Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa. Atmospheric pressure is also often stated as pounds/square inch (psi). The atmospheric pressure at sea level is 14.7 psi.

## Which of the following represent average atmospheric pressure at sea level quizlet?

For example average sea-level air pressure is approximately 1000 mb. At the altitude where the pressure is 500 mb half of the mass of an atmospheric column would be below and half above.

## What is the name of the gradient between high pressure and low pressure?

The change in pressure measured across a given distance is called a “pressure gradient”. The pressure gradient results in a net force that is directed from high to low pressure and this force is called the “pressure gradient force“. The pressure gradient force is responsible for triggering the initial movement of air.
