I use the smallest of the three nesting SnowPeak pots. I have to be careful when stirring because it is quite full. I also take the lid. Sometimes we take the middle sized pot if we feel very decadent. Sorry, but I do not know what the liter capacity is for the pots. The small pot has a "1000" marking a bit less than half an inch from the rim and it is 6 inches diameter. I suppose that is a bit over a liter capacity.

By the way, I really cook, not just boil water. We boil water, pour hot drinks (usually miso soup- tiatnium cups) then cook dinner and eat with the pot between us. I think I get less than half of the meal - my significant other eats faster than me! We do add a fairly large frying pan when we seriously fish.
