Anyone know of an online source of a table to convert BAR to PSI and vice versa?
|
|
try search engine ask.co.uk and type in "convert bar to psi" and it will come up with a few sites.
|
1 bar = 14.5 lb/square inch

As John Slaughter says, 1 bar (=1 atmosphere pressure) = 14.5 psi, and as many cars use tyre pressures between 27 and 31 psi , this equals 1.9 to 2.1 bar. Anyway, most cars quote both values, either in the handbook or on the driver's door or somewhere else. Is there a particular problem?

Many thanks for the information. The problem was that my newly acquired mini-compressor, which works off the car's ciggy lighter measures in psi but the VW handbook and petrol cap sticker express pressures only in bar. And it surprised me that this was missing from the otherwise comprehensive unit conversion utility on my computer (part of the value-packed Oxord Reference Shelf, with its 16 dictionaries and other works of reference).

The accuracy of your 12volt compressor will be so inaccurate the any conversion will be irelavent.
Just abour every tyre center I have seen displays pressure in both bar and psi

Trevor, I pumped my rear MPV tyres to 4 bar because the handbook said 40 psi fully loaded and I was a clot. (I hate people who throw fag ends onto the road because it makes it so bumpy!)
