What is the metric measurement of pressure?
I'm traveling to Europe and I'd like to know how tire pressure is measured on the continent? What is the metric equivalent of of pounds per square inch (psi)? I won't be bringing a tire gauge with me so I'd like to know what 85psi is in metric terms.

There are several different pressure units including torr, atmosphers, and bar but the most basic one is the pascal or kilopascal. Having never filled a tire in Europe, this is what I assume they would use for tires.
1 psi = 6.895 kilopascals
0r
6895 pascals
1 psi = 6.895 kilopascals
0r
6895 pascals

85psi in UK is 85psi.
everywhere else its about 6 bar

The pressure unit derived from the metric system is the pascal: it is defined as one newton per meter squared, where a Newton is the metric unit of force (kilogram meter per second squared). I think the real point of your question was answered previously, but I'm a mineral physicist and specialize in experimentally producing ultra-high pressures... couldn't resist 
Oh, as another poster pointed out, the typical scientific notation prefixes are used for the Pascal as well (e.g. nano, micro, mili, kilo, mega, giga, etc), for convenient notation spanning many orders of magnitude.

When I went into a LBS in Ireland to get a new tire, the guy there talked in psi language. Even though they may use 'bars', I think 'psi' is kind of universal?
