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 a bar? The bar is a unit of pressure approximately equal to atmospheric pressure at sea level, defined as exactly 100,000 pascals or 100 kilopascals. The bar definition makes it widely used in meteorology, oceanography, and engineering, particularly in Europe. Although not an official SI unit, the bar is accepted for use with SI units and provides a convenient scale for measuring pressures near atmospheric pressure.

Converting bars to other pressure units is essential for meteorology, engineering, and industrial applications. One bar equals 100,000 pascals, 100 kilopascals, approximately 14.5038 pounds per square inch (psi), 0.986923 atmospheres, or 750.062 torr. Bar conversions are fundamental to pressure measurements, whether you're using a bar converter tool, learning how to convert bars, or performing bar to other units calculations. The bar's relationship to atmospheric pressure makes it intuitive for many applications, providing a convenient unit for pressures near standard atmospheric conditions.

The bar is extensively used in meteorology, oceanography, engineering, and industrial applications. A bar converter is valuable for pressure calculations, engineering design, and weather measurements. Meteorologists measure atmospheric pressure in bars or millibars. Oceanographers measure water pressure in bars. Engineers use bars for system pressures and fluid dynamics. The bar's relationship to atmospheric pressure makes it essential for many applications, making bar converter tools valuable resources for professionals in meteorology, oceanography, and engineering.
