Does anyone know of a more dense handheld calculator?
I have no scales and rulers that measure in "oz." an "in." (and have so far been unable to figure out how the "units" function of the HP48 works), therefore I cannot provide any numbers for comparison, but I can offer a few candidates.
This little no-name titanium coloured currency converter must be the most dense calculator in my collection:
Subjectively, it feels like a piece of matter ejected from a neutron star. Mass and dimensions (the thickness is difficult to measure because it has an airfoil shape) are 200g 11,5 x 4,7 x 0,8 cm^3. This results in a density of 4,65 g/cm^3 which is almost equal to that of the titanium that it mimicks.
Two other calculators with above-average density are the Aristo M27 (one of my three top favorites, it is bareley larger than the five AA batteries that it holds and feels very solid, but figures from the internet give a density of only 1,5 g/cm^3) and the silver-plated Sinclair Sovereign.
And the most likely candidate from HP would be the HP-01 although I do not want to immerge mine in water to determine its volume.
