John,...I agree.  I heard that the Canadian guages are in

Kg/cm2 which is a real hodge-podge.  Pressure has units of

force/area.  Kg is mass.  The English system often makes

the mistake of using a force unit (lb) to indicate mass (slug)

but this is the first time I've seen an instance of using

a mass unit (kg) to indicate a force (newton). No doubt they

mean the force of gravity upon a 1 kg mass.

(1 newton - 1kg* 1m/sec2)



The REAL unit to use is the Pascal ( = 1newton/m2) which is

a very small pressure.  KiloPascals would be more appropriate.
