	Pascal (SI unit)	Bar	Technical atmosphere	Standard atmosphere	Torr (mmmercury)	Pound-force per square inch
1 Pa	≡ 1 N/m²	= 10-5 bar	≈ 10.197×10−6 at	≈ 9.8692×10−6 atm	≈ 7.5006×10−3 torr	≈ 145.04×10−6 psi
1 bar	= 100 000 Pa	≡ 106 dyn/cm²	≈ 1.0197 at	≈ 0.98692 atm	≈ 750.06 torr	≈ 14.504 psi
1 at	= 98 066.5 Pa	= 0.980665 bar	≡ 1 kp/cm²	≈ 0.96784 atm	≈ 735.56 torr	≈ 14.223 psi
1 atm	= 101 325 Pa	= 1.01325 bar	≈ 1.0332 at	≡ 101 325 Pa	= 760 torr	≈ 14.696 psi
1 torr	≈ 133.322 Pa	≈ 1.3332×10−3 bar	≈ 1.3595×10−3 at	≈ 1.3158×10−3 atm	≡ 1 mmHg	≈ 19.337×10−3 psi
1 psi	≈ 6894.76 Pa	≈ 68.948×10−3 bar	≈ 70.307×10−3 at	≈ 68.046×10−3 atm	≈ 51.715 torr	≡ 1 lbf/in²
