Hmmm. Something fishy here. The Kg is not a unit of weight, it is a unit of mass. The 2.2 conversion between pounds and Kilo-grams is only valid in earth's gravity (9.8M/s2). The metric unit of weight is a Newton (N=KgM/s2). The correct units should be N/cm2. This would be a mixture of SI and CGS, but it should only concern purists. ttfn David Pearson Nortel, Public Carrier Networks Northern Telecom Ottawa, Ontario, Canada dpearson@no*.ca* In message " Dive Cylinder ID", rnf@sp*.tb*.co* writes: > >> DALMINE >> ARIA 150kg/cm2 >> 10 litre 10 kg 19-3............ >> >> Any info is appreciated.
