Re: [Phys-l] Fun/cool unit conversion example?

Talking of recherche conversions, recall that John D offered the capacitance of a 1 cm sq capacitor and the inductance of a 1 turn coil of diam 1 meter.
If these are resonated together, what nuclear resonance of an isotope of a common gas is mimicked in a NMR spectrometer which uses a 500 MHz magnet? :-)

On the first day of class I do a brief example to illustrate unit conversion (snore) and I usually spice it up by making it very silly (such as density measured in gigaslugs per parsec cubed).

I thought I would ask here to see if anyone had a neat unit conversion example that left you with a sense of "huh, I didn't know that" or "that was cool!" or something similar.
I tell them Benjamin Franklin was famous for hiding oil in the joint of his bamboo cane and then "calming the waters" of a troubled pond by releasing the oil on it. Turns out that one teaspoon of oil spreads out to cover about 0.5 acre of pond. /snip/
