Not that simple. You also need to know the compressed gas pressure, and apply the Charles and Boyle ideal gas laws to figure out an approximation. The rated volumes are for the amount of gas the cylinder contains at the nominal fill pressure, when expanded to standard temperature and pressure. (basically sea level and room temperature)
