SEC: UNCLASS NEC-LIST: Imperial and metric units and the like

Dear NEC-listers ...

        I note the following entry in Stephen Dresner's "Units of
Measurement" (SBN 85602 002 8):

"CROCODILE

Quantity: Electric potential and potential difference, electromotive force
(metric)

Definition: 1 crocodile = 10^6 volts (V). 1V = 10^-6 crocodile

Note: This unit is employed at an informal level in a number of UK nuclear
physics laboratories."

Thus, for what it is worth, we could specify electric field strength in
crocodiles/fathom.

Harry,

1.8*10**12 should be the distance travel by light in furlongs per fortnight.

To make the unit more interesting or confusing, we know

1 kilometer = 1000 meters
1 kilometer = 4.97097 furlongs
1 furlong = 6.6 engineer's chain
1 engineer's chain = 1.51515 chain (surveyor)
1 chain (surveyor) = 4 rod, pole or perch
1 rod, pole or perch = 2.75 fathom
1 fathom = 1.8288 meter

Hence,

1 furlong = 4.97097 * 6.6 * 1.51515 * 4 *2.75 * 1.8288 meter !

Regards,
Roger Tay

Dear NEC-lister,

Any that are determined not to metricate may find the following
information useful. The velocity of light in furlongs per fortnight is
1.80*10**12. While not in widespread engineering use, this well
pedigreed imperial unit does have a certain poetic appeal.

Sincerely,
Harry E. Green
