Lenntech BV is not responsible for programming or calculation errors on this sheet. 1 bar is equal to 100,000 Pascals, which is close approximately to atmospheric pressure, so it is often used to represent atmospheric pressure rather than standard. It is widely used in the daily life particularly in European countries, though that is a non-SI unit. The constant c is equal to the amount of gas in moles, multiplied by the gas constant: 14.50377 Psi (Psi) Bar : The bar is a unit of measurement for pressure. These conditions are often fullfilled, for example for air at atmospheric pressure and standard temperature. This formula is called the ideal gas law.It is valid if the temperature (in kelvin) is at least 50% higher than the temperature at the critical point and the pressure does not exceed the critical pressure. This is because the molecules get more energy and move faster.Ĭ is a constant, proportional to the number of gas molecules To convert Bars (bar) to Pounds per Square Inch (psi), you just need to know that 1bar is equal to 14.5 psi. If the volume is constant and the temperature increases, the pressure also increases. The pressure of a gas is related to temperature and volume. Relation between temperature, pressure and volume (ideal gas law): If you measure the pressure in Pascal at sea-level, you will find 101325 Pa. At sea-level the pressure is also defined as 1 atmosphere, that's why 1 atmosphere equals 760 torr. It was calibrated that on sea-level the height of the mercury was 760 mm. The reason that mercury is used is that the thermal expansion of mercury is big and is mostly homogeneous. If the pressure changes, the level of the mercury in the tube changes with it. 25-901-60-bar/psi-G1/4 - 2-1/2 (63mm) dial liquid-filled dual-scale pressure gauge with bar (primary) & PSI (secondary) markings - glycerin-filled - NOSHOK. This point of conversion is multiplication by 14.504. The unit of pressure used to be torr, also known as mmHG (millimeter mercury). This can be done by finding their mutual point of conversion. The unit is Pascal (Pa), also known as N/m 2. Pressure ( p) is a derived quantity with its own name. Use this conversion calculator to convert American/Britis units to the metrical (SI) units.
