Are you trying to keep this thread off topic because you have no idea how to support the notion that the moon landings were faked?

No, I am just mystified of you using a barometer inside a submarine. Or inside an aeroplane with pressurized interior for that matter. But, OK. You are interested in the density of air and YES, it depends on the air pressure recorded by e.g. a barometer or pressure gauge. I am happy that we agree on this point. FYI, the air pressure on the Moon is 0 due to lack of air there. That's why there are no barometers on the Moon.
