Pascal and kilopascal are units of the International System. Bar and atmosphere are common in meteorology and diving, psi is used mainly for tire pressure in the United States, and millimeter of mercury (mmHg) shows up in weather forecasts and blood pressure readings. One bar equals 100,000 pascals; the other conversions between these units are detailed in the frequently asked questions below.
