What are the various units of pressure? Show how to convert one pressure unit into another using dimensional analysis. The formal, SI-approved unit of pressure is the pascal (Pa), which is defined as 1 N/m2. A common unit of pressure is the atmosphere (atm), which was originally defined as the average atmospheric pressure at sea level. A more reliable and common unit is millimeters of mercury (mmHg), which is the amount of pressure exerted by a column of mercury exactly 1 mm high. An equivalent unit is the torr, which equals 1 mmHg. What are the various units of pressure? Show how to convert one pressure unit into another using dimensional analysis.
