What is a millimeter of mercury? The millimeter of mercury (mmHg) is a unit of pressure representing the pressure exerted by a column of mercury one millimeter high under standard gravity. The millimeter of mercury definition makes it commonly used in medicine for measuring blood pressure and in chemistry for pressure measurements. One mmHg equals approximately 133.322 pascals or 1 torr.

Converting millimeters of mercury to other pressure units is essential for medical applications, chemistry, and scientific research. One millimeter of mercury equals approximately 133.322 pascals, 0.133322 kilopascals, 1 torr, approximately 0.0193368 pounds per square inch (psi), or 0.00131579 atmospheres. Millimeter of mercury conversions are fundamental to pressure measurements in medicine and chemistry, whether you're using a millimeter of mercury converter tool, learning how to convert millimeters of mercury, or performing millimeter of mercury to other units calculations. The millimeter of mercury's historical relationship to mercury manometers makes it deeply embedded in medical and scientific practice.

The millimeter of mercury is extensively used in medicine for measuring blood pressure and other physiological pressures. A millimeter of mercury converter is valuable for medical applications, pressure calculations, and scientific measurements. Medical professionals worldwide use mmHg for blood pressure readings. Chemists use mmHg for pressure measurements in laboratory work. The millimeter of mercury's historical relationship to mercury manometers makes it essential for medical and scientific practice, providing a standard unit for physiological and chemical pressure measurements, making millimeter of mercury converter tools valuable resources for medical professionals and researchers.

What is PSI? PSI (pounds per square inch) is a unit of pressure in the British imperial and US customary systems, representing the pressure resulting from a force of one pound-force applied to an area of one square inch. The PSI definition makes it widely used in the United States and United Kingdom for measuring pressures in engineering, automotive, and industrial applications. One PSI equals approximately 6,894.76 pascals or 0.0689476 bars.

Converting PSI to other pressure units is essential for engineering, automotive, and industrial applications, especially for international communication. One PSI equals approximately 6,894.76 pascals, 6.89476 kilopascals, 0.0689476 bars, 0.068046 atmospheres, or 51.7149 torr. PSI conversions are fundamental to pressure measurements in countries using imperial units, whether you're using a PSI converter tool, learning how to convert PSI, or performing PSI to other units calculations. The PSI's practical scale makes it ideal for everyday pressure measurements in countries using imperial systems.

PSI is extensively used in the United States and United Kingdom for automotive, engineering, and industrial applications. A PSI converter is valuable for pressure calculations, engineering design, and automotive applications. Tire pressures are measured in PSI. Hydraulic systems and pneumatic systems use PSI for pressure specifications. Industrial equipment measures operating pressures in PSI. While most of the world uses metric pressure units, PSI remains deeply embedded in American and British engineering and automotive industries, making PSI converter tools valuable resources for professionals and consumers.
