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.
Answer
Pressure is defined as force acting per unit area of the surface.

= 1.01332 × 105 kg m–1s–2
We know,
1 N = 1 kg ms–2 Then,
1 Pa = 1 Nm–2 = 1 kg m–2s–2
1 Pa = 1 kg m–1s–2
1 Pressure = 1.01332 × 105 Pa
1Pa = 1N m–2
If mass of air at sea level is 1034 g cm–2, calculate the pressure in Pascal.
