Give relation between different units of pressure.

Explanation

(i) 1 Pa = 101.325 k Pa
(ii) 1 atm = 101.325 k Pa = 101325 Pa = 101325 `Nm^(-2)`
1 atm `= 10^(5)` Pa = `10^(2)` k Pa
(iii) 1 bar = 0.987 atm = 14.509 psi
1 atm = 1.01325 bar
1 bar `= 1xx10^(5)Nm^(-2)=10^(2)kPa = 10^(5)` Pa
(Note : Some times it is taking 1 bar = 1 atm, but it is not complete right)
(iv) 1 atm = 76 cm Hg
= 760 mm Hg
= 760 torr
1 torr = 1 mm Hg
