Base metabolism

xaryo

I know (and physicaly tested it) that at rest ( sitting on the couch), my body metabolise 0,6 liter of oxygen per minute.

With that data and my weight, is it possible to calculate my base metabolism, at least more accuratly than some general data from approximation?

I calculated my consumption while calibrating the oxygen flow for my closed-circuit rebreather ( scuba diving without bubbles).
