The metric units we usually use are KPa, MPa, and bar. The unit of pressure is Pascal, which is "Pa", 1 Pa is equal to 1 N of force acting on an area of 1 square meter, that is, 1Pa=1N/m². Metric Units: KPa, MPa, Barįirst, 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. Next, I will explain the conversion method of pressure units KPa, MPa, bar, psi, and Kg in detail for you. Different countries and regions use different units, so in international trade, it is very important to convert the two to achieve unity. Pressure units are divided into metric units and imperial units. Among them, the pressure unit is essential, and there will be relevant descriptions in the design, application, and product characteristics. Water - Properties at Gas-Liquid Equilibrium Conditionsįigures and tables showing how the properties of water changes along the boiling/condensation curve (vapor pressure, density, viscosity, thermal conductivity, specific heat, Prandtl number, thermal diffusivity, entropy and enthalpy).Valve and pipe fitting systems have many important parameters.

Involving velocity, pressure, density and temperature as functions of space and time. The SI-system, unit converters, physical constants, drawing scales and more. Note! - pressure is "force per unit area" and commonly used pressure units like kg/cm 2 and similar are in principle not correct since kg is a mass unit.
