Please provide values below to convert kilopascal [kPa] to psi [psi], or vice versa. Definition: A kilopascal kg cm2 en mpa kPa is a multiple of the pascal Paan SI International System of Units derived unit of pressure used to measure internal pressure, Young's modulus, stress, and ultimate tensile strength.

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. The Boltzmann constant and the Avogadro constant were similarly determined, which separately relate energy to temperature and particle count to amount of substance.

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. See Water and Heavy Water for thermodynamic properties at standard condtions.

Density of crude oil , Density of fuel oils , Density of lubricating oil and Density of jet fuel as function of temperature. As shown in the figures, the change in density is not linear with temperature - this means that the volumetric expansion coefficient for water is not constant over the temperature range. Water density, specific weight and thermal expansion coefficient at temperatures given in degree Celcius:.

In classical statistical mechanicsthis average is predicted to hold exactly for homogeneous ideal gases.

Pressure is usually defined as the amount of force applied to a certain area. While we have already discussed everything about pressure in our earlier article, we will explore the topic of units of pressure. We will look at what is the unit of pressure by first learning about the SI system, which is the International System of Units, derived from the metric system.

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.

The constant is also a combination of the constants from Boyle's law , Charles's law , Avogadro's law , and Gay-Lussac's law. Exceptions include certain countries that use either the imperial or United States customary systems of measurement, such as the United States, in which the unit of pound per square inch is more commonly used. National Aeronautics and Space Administration. Density is the ratio of the mass to the volume of a substance:. What is pressure? SI units. Avogadro constant Boltzmann constant Gas constant.

San Francisco: W. On the elasticity of gases. Exceptions include certain countries that use either the imperial or United States customary systems of measurement, such as the United States, in which the unit of pound per square inch is more commonly used. Introduction to Microfluidics. Prentice Hall. Current use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. Further information: Entropy statistical thermodynamics. The characteristic energy kT is thus the energy required to increase the rescaled entropy by one nat. 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. Psi means "pound per square inch", which means 1 pound of force acts on an area of 1 square inch. Pressure units are divided into metric units and imperial units.
