# Pressure of 1 Atm _________ Pa

Pressure of 1 Atm 1.013 x 10 5 Pa.

## Pressure

The pressure is thrust per unit area, hence it is directly proportional to thrust and inversely proportional to area. Tpressure is a scalar quantity that is it has only magnitude but no direction. Pressure can be either a positive or negative value.

Bar and Atm are the units representing pressure. A pascal is one newton of force acting on the 1m2 area.

### Relation Between Bar and Atm

The relationship between Bar to ATM can be expressed as

1 bar = 0.986923 atm

or

1 atm = 1.01325 bar

1 atm pressure exerted by the column atmosphere at sea level.

1atm=101.325 kPa
