I use an include file I made which has conversion factors for a wide variety
of units.  I simply include the file at the beginning of my scene, and then
I multiply the measurement by the name of the unit the measurement is in.
It defaults to 1 POV unit = 1 centimeter, but that can be changed, by
redefining the centimeter.  For example:

#declare cm = 1/100;    /* 1 POV unit = 1 meter */
#include "units.inc"
sphere{
    -5*y*feet, 67*inches
    pigment{ bozo scale feet }
    finish{reflection .5}
    translate x*-17*cm+y*2*yards
}
plane{y, -1*millimeters pigment{checker scale Decimeter}}
camera{location 0.0025*km look_at y*1000*1000*1000*Angstrom}
light_source{1, 93*1000*1000*miles}

The file's at http://www.geocities.com/Rengaw03/povray.html (called
Units.zip)
