Convert Pascal to Centimeter of Mercury (Pa to Centimeter of Mercury)

Pascal (Pa) and Centimeter of Mercury (Centimeter of Mercury) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert pascal to centimeter of mercury. This free online calculator tool makes it simple and easy to perform the conversion from Pa unit to the Centimeter of Mercury unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

A pascal (Pa) is the SI unit of pressure, equal to one newton per square metre (1 N/m²). Named after the French mathematician and physicist Blaise Pascal, the pascal measures the amount of force applied over a given area. It is the standard unit for pressure, stress, and elastic modulus in science, engineering, meteorology, and many industrial applications.

One pascal represents a relatively small amount of pressure, so larger multiples such as kilopascals (kPa), megapascals (MPa), and gigapascals (GPa) are commonly used in engineering and industry. The pascal is part of the International System of Units (SI) and provides a consistent standard for pressure measurements worldwide.

Pascals are widely used to measure atmospheric pressure, fluid pressure, tire pressure (often expressed in kilopascals), material strength, hydraulic systems, and engineering calculations. The unit also plays an important role in structural engineering, mechanical design, aerospace, and scientific research.

The centimeter of mercury (symbol: cmHg) is a non-SI unit of pressure based on the pressure exerted by a one-centimeter column of mercury under standard gravity. It has traditionally been used in scientific instruments, laboratory measurements, and vacuum systems. Although the pascal is the SI unit of pressure, the centimeter of mercury is still encountered in specialized applications. It is closely related to the Torr and other mercury-based pressure units.

One centimeter of mercury is equal to 1,333.22 pascals, 10 millimeters of mercury, 0.0133322 bar, 0.193367 psi, and 0.0131579 standard atmosphere. This unit remains useful for comparing pressure values in traditional measurement systems.
