Volume
1 Litre= 10³ mL= 10³ cm³= 10⁻³ m³= 1 dm³

Pressure
1 atm= 76 cm of Hg= 760 mm of Hg= 760 torr
1 atm= 1.01*10⁵ Nm²
1 atm= 1.01*10⁵ Pa
1 bar= 0.9862 atm≈ 1 atm

PV=nRT
or, PVT⁻¹ = constant = nR
R= Universal Gas Constant

[R] = Lit atm K⁻¹ mol⁻¹ = work done per Kelvin per mole
R= 0.0821 Lit atm K⁻¹ mol⁻¹
R= 8.314 J K⁻¹ mol⁻¹ = 8.314 Pa cm³ K⁻¹ mol⁻¹
R= 1.987 cal K⁻¹ mol⁻¹
R= 5.189* 10¹⁹ eV K⁻¹ mol⁻¹

According to Dalton's Law of Partial Pressure,
P = P₁+P₂+­P₃+.....+Pₙ = ΣPₙ
Where P is the total pressure and P₁, P₂, P₃... are the partial pressures of gases 1, 2, 3 and so on.

P₁= P*x₁
where x₁ is the mole fraction of gas 1.
