![]() The units can be used at any time be converted. Problems can also arise when working with tables or instructions that have been created with the help of units customary abroad. Problems only arise when an old measuring instrument is used which uses a unit that is no longer in use. There are also some regional differences between the im Anglo-American area used imperial unity and the European System. Science and technology have continued to develop over the years. There are various historical reasons why a wide variety of units are used to determine pressure. If the conversion takes place in the same technical context, the result is always correct according to the conversion factors as described above. With the unit psi or bar it does no differencewhether there is overpressure or absolute pressure. That plays a role in a conversion none Role. Will be a car tire with a pressure of 3 bar inflated, it is actually a pressure of to CE standards. For this reason it is also called Overpressure bezeichnet. ![]() The pressure gauge of your compressed air compressor or your bicycle pump shows the pressure that above normal ambient air pressure goes out. For example, a bar means the air pressure at sea level. The measurement bar was from the average atmospheric pressure derived from the earth. Information about printing and overprinting! The other way around you can use the psi value 0,069 multiply by the bar value to obtain. If you need to convert a bar value into psi, simply multiply the value with 14,504th. If you know the conversion factor, the different units are no longer a big problem. If 40-65 psi is on a tire, the pressure gauge displayed on your foot pump should be between 2,76 to 4,48 bar Show. ![]() Mixing up the units could have serious consequences. They can be found on many objects that are needed every day. You can use a Conversion tablehelp to determine the correct value. If the pressure tester uses a unit other than that specified on the tire, for example, must converted become. Yamaha präsentiert brandneue E-Bike Modellpalette: MORO 07, Wabash RT und CrossCore RC!
