"Atmosphere" call pressure unit of measure which is not entering the international SI system and equal to the atmospheric pressure measured on global sea level. Exact numerical determination of this unit has two incoincident values, one of which is called the "standard" or "physical" atmosphere, and another - the "technical" atmosphere. Bar - other stand-alone unit of measure of pressure used in domestic state standard specifications.
Instruction
1. Determine which of types of the atmospheres, as units of measure, has to be used for converting of the value which is available for you measured in bars. Technical atmosphere is defined as the mechanical tension caused with a force of some among "kilograms of force" (kgf), directed perpendicularly to a surface in one square centimeter and distributed on it evenly. In used in the international SI Paskalyakh system this size 98066.5 units equal. And one physical atmosphere in the same units equals 101325 units and is defined how force counterbalancing pressure of 760 millimeters of a column of mercury with a density of 13595.1 kg/m² at a temperature of zero degrees Celsius.
2. Use a ratio of 1 bars = 1.0197 atmospheres if it is required to receive result of converting in the technical atmospheres. If it is necessary to transfer bars to the physical atmospheres, then apply a ratio of 1 bars = 0.98692. For example, to translate pressure equal to 150 bars, in the technical atmospheres, this number should be increased by 1.0197 (150∗1.0197=152.955). Converting of the same pressure in the physical atmospheres will give the number equal 148.038 (150∗0.98692=148.038).
3. Use the calculator for practical calculations. It not necessarily has to be the separate gadget or the program calculator which is available in the operating system. If you have an Internet access, then the calculator posted on any website is the simplest to use. To look for it there is no need as also search engines have the built-in calculators. For example, you can pass to the website of Nigma search engine and enter inquiry "150*1.0197" to transfer 150 bars to the technical atmospheres. After sending request for the server receive result: 152.955.
