Comparisons as pressure
≈ 0.41 × typical pressure inside a domestic LPG cylinder with 70% propane and 30% butane at 20 degrees Celsius ( 3 kPa )
≈ (0.1 to 1.2) × approximate explosion peak overpressure needed to break a glass window ( 1000 to 10000 Pa )
≈ (1.1 to 1.9) × atmospheric pressure on the surface of Mars ( 0.007 to 0.01 bar )
