WebApr 12, 2024 · Torr is equal to 1 mmHg in a barometer and 133.322368 in pascals. So, torr is equal to two units, i.e., torr in mmHg and torr in Pascal. This unit is based on the absolute scale, which is 1/760 of the standard pressure unit, i.e., 1 atm or one atmospheric pressure. One atmospheric pressure or atm is equal to 1.01325 kPa. WebExample: A car tire gauge measures a tire pressure of 32.0 psi. The local atmospheric pressure is 14.2 psi. What is the absolute pressure of the air in the tire? Solution: The tire gauge measures gage pressure, relative to the local value of atmospheric pressure. Thus, p = p g + p a = 32.0 + 14.2 psi = 46.2 psia. Note that in the English system ...
