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

Hi all,

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 personally like

1. The following is taken from "The Japan Times Weekly International Edition" of May 7-13, 1990.

"The most expensive land in Japan as of last Jan. 1 was located in Tokyo's downtown areas of Ginza and Marunouchi - worth 37.7 million Yen per sq. meter in both areas, according to a National Land Agency report on government-assessed land prices nationwide."

The article then quoted the cost, in dollars, of a piece of land the size of a postage stamp in either of these areas. Given that a postage stamp measures 7/8" x 31/32", what price should they have stated?

(Round your answer off to the nearest whole dollar.)
