Pressure is determined as force per unit area of the surface. The SI unit of pressure, Pascal is as shown below:
1Pa = 1N m–2
If mass of air at sea level is 1034 g cm–2, calculate the pressure in Pascal.
Given:
Pressure = Force/Area
= 
= 1.01332×105 kg/m/s2
We know that,
1N = 1km/ s2
1 Pa = 1 kg/m-2/s2
= 1 kg/m-1/s2
Therefore, Pressure in Pascal =1.01322×105 Pa
