WebMercury (Hg) density is 13.5951 g/cm 3 (133595.1 kg/m 3 ), and the standard gravity is 9.80665 m/s 2. Also, note that 120 mm is 0.12 m. Pressure = 13595.1 kg/m 3 × 9.80665 m/s 2 × 0.12 m = 15998.69 Pa Now we obtain the relation between 1 Pa and 1 mmHg. Let’s consider 1 atm = 1,01,325 Pa, and 1 atm = 760 mmHg (As discussed earlier).
