Pressure is expressed in the unit atm.
Its value in pascal(P) is-
1 atm = 1.01325 × 10^5 pascals
Its value in pascal(P) is-
1 atm = 1.01325 × 10^5 pascals

Atmospheric pressure= Force of the atmosphere/ Surface of the Earth,
The weight applied on the surface area of 1cm² on the earth is the atmospheric pressure.
Atmospheric pressure=P₀=mg/A
=1kgx10m/s²/ 1 cm²
=10N/cm²
=10⁵N/m²
1 atm=10⁵ Pascal.
Hence Atmospheric pressure is the physical quantity which is expressed as atm
