Pressure Converter
Convert pressure between pascals, kilopascals, bar, pounds per square inch (psi), standard atmospheres, millimeters of mercury (mmHg), and torr. Pressure shows up in tire inflation, weather forecasts, scuba diving, plumbing, and science, and every field seems to prefer a different unit. This converter uses the standard defined relationships so you can move between them confidently, for example one standard atmosphere equals 101325 pascals and one bar equals exactly 100000 pascals. Select the unit you have and the unit you want, type a value, and the result updates live as you type. It runs entirely in your browser, so answers are instant, your input stays private, and the tool remains usable even without an internet connection.
