From this end of the world we are used to think in International Standards.
I can calculate from cm into inches, but from Celsius in Fahrenheit is
already too difficult for me. Not to mention al the other alien measurement
standards you people are using.

However, Europeans measure in atu, not atm and that is 1kgf/cm2. This
is called a "technical atmosphere" because 14.7lb/in2 is at sea level
at some time or another. (1 atu = 14.2 psi) I don't know what units
bicycle tire people are talking about but automotive use atu's.
