I'm no mathematician, so I asked ChatGPT to calculate the number of refills I can get from a 6.8L bottle to a 0.3L bottle

I'm not trying to be a smart ass, the use of different units of measurement can be confusing, at least to me. Apparently 6.8l=74cu=45min regarding these SCBA tanks.

It is a bit confusing because when designating a tank size in liters, the true volume of the tank is used (how much liquid it can hold).

When designating in cubic feet, it’s how much air AT ATMOSPHERIC PRESSURE the tank will hold.

In liters, pressure is not accounted for in the designation.
