This table is from the encyclopedia of recreational diving. (rev 01/17 version)
I don't understand how they calculated the full capacities for the hp cylinders at the bottom (specifically the metric values) did they use 300 bar instead of 327 by accident? Also how would the smaller cylinder have a larger capacity for the same rated pressure (2nd row from the bottom)
All in all this table has me very confused and pretty sure there are some errors in here somewhere.
