I am aware that in some places, the Texas is a preferred measure of area. It is my opinion that the Texas is less intuitive even than the Belgium or the Wales, which at least have a fairly regular shape. Anyone who can tesselate Texii in their head is clearly a genius anyway. In an attempt to stamp out this unit of measurement, the Texas was omitted.
For the lunatics I have seen using the Somalia and Upper Volta as measures of area: really, no. Just no.
Perhaps I should explain the Titanic weights. This is not the weight of the Titanic, but the weight it can take before sinking, c.34000 tons. (5607 male African elephants). I don't know how accurate this is, but I am confident it is close enough to say "Gosh, with that amount of [baked beans, etc.] you could sink the Titanic [a certain number of] times!!1!" and so forth.
I almost included the lung as a unit of area, but on reflection the lung is always expressed in terms of tennis courts. (about half the size of a singles court, contrary to many places that will tell you that 100m2 is about one tennis court. Maybe they mean one side of the net.)
If it helps you, substitute "bag of sugar" for "kilogram".
