Please provide values below to convert kilopascal [kPa] to psi [psi], or vice versa.

The molar gas constant also known as the gas constant , universal gas constant , or ideal gas constant is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant , expressed in units of energy per temperature increment per amount of substance , rather than energy per temperature increment per particle. The constant is also a combination of the constants from Boyle's law , Charles's law , Avogadro's law , and Gay-Lussac's law. It is a physical constant that is featured in many fundamental equations in the physical sciences, such as the ideal gas law , the Arrhenius equation , and the Nernst equation. The gas constant is the constant of proportionality that relates the energy scale in physics to the temperature scale and the scale used for amount of substance. Thus, the value of the gas constant ultimately derives from historical decisions and accidents in the setting of units of energy, temperature and amount of substance.

Valve and pipe fitting systems have many important parameters. Among them, the pressure unit is essential, and there will be relevant descriptions in the design, application, and product characteristics. Pressure units are divided into metric units and imperial units. Different countries and regions use different units, so in international trade, it is very important to convert the two to achieve unity. First, we must realize that pressure does not force, the unit of pressure is N, and pressure refers to the vertical force on the unit area of an object. The metric units we usually use are KPa, MPa, and bar. The imperial unit we usually use is psi. Psi means "pound per square inch", which means 1 pound of force acts on an area of 1 square inch. It seems very complicated, but in fact, the conversion in daily life is generally between psi and bar, and between bar and MPa. Then comes the introduction of Kg kilogram.

Density is the ratio of the mass to the volume of a substance:. Specific weight is the ratio of the weight to the volume of a substance:. In the Imperial system the mass unit is the slug [sl] , and is derived from the pound-force by defining it as the mass that will accelerate at 1 foot per square second when a 1 pound-force acts upon it :. The density of water is 1. See more about the difference between mass and weight. The calculator below can be used to calculate the liquid water density at given temperatures.

To switch between the two conversions, simply use the swap icon rotating arrows. If you need to start over, you can reset the values by clicking the reset button. Article Contents [ show ]. Megapascal MPa is a metric unit of pressure commonly used in engineering and physics. It is defined as one million pascals, which is equivalent to one newton of force per square millimeter. Megapascals are often used to measure high-pressure systems, such as hydraulic systems, structural engineering , and materials science. For example, the strength of a material can be determined by measuring the stress it can withstand per unit area in MPa. Megapascals can be converted to other units of pressure, such as bar, psi, and atmospheres, using conversion factors.

The specific gas constant of a gas or a mixture of gases R specific is given by the molar gas constant divided by the molar mass M of the gas or mixture:. Download as PDF Printable version. As another example, the definition of thermodynamic entropy coincides with the form of information entropy :. Contents move to sidebar hide. Modify the access date according your visit. Your Mobile number and Email id will not be published. The value of R is then obtained from the relation:. Kotomin, St. There are several other units of pressure such as pounds per square inch and bar, unit of atmospheric pressure is atm, centimetres of water, millimetres of mercury or inches of mercury used as a unit of blood pressure , torr, MSW and FSW. Note the use of kilomoles, with the resulting factor of in the constant. Based on a mean molar mass for dry air of From: kilopascal To: psi. Form Reference:.

There was considerable disagreement in the second half of the nineteenth century as to whether atoms and molecules were real or whether they were simply a heuristic tool for solving problems. Modify the access date according your visit. This corresponds very well with experimental data. The gas constant is the constant of proportionality that relates the energy scale in physics to the temperature scale and the scale used for amount of substance. In , at the 14 th General Conference on Weights and Measures, the pascal was adopted as an SI derived unit of pressure. Archived from the original PDF on 5 March Tools Tools. Kinetic And Potential Energy. Its full name is pressure nominal, the unit is MPa. Before that pressure in SI was measured in newtons per square metre. The characteristic energy kT is a term encountered in many physical relationships. What is the CGS unit of pressure?
