Depth of water d giving gauge pressure p_e from p_e = ρ_(H_2O)gh: | 0.68 inches | 17 mm (millimeters) | (assuming conventional water density ≈ 1000 kg/m^3)

Standard Atmosphere altitude: | 27 miles | 44 km (kilometers) | (based on 1976 US Standard Atmosphere)

≈ ( 0.056 ≈ 1/18 ) × typical pressure inside a domestic LPG cylinder with 70% propane and 30% butane at 20 degrees Celsius ( 3 kPa )

≈ (0.1 to 0.2) × atmospheric pressure on the surface of Mars ( 0.0066 to 0.011 bar )

≈ 0.28 × partial vapor pressure at the triple point of water ( 611.7 Pa )
