#3037 HP to Watts

Orcinus orca · 25 October 1991

Richard, nearly everything in the aero- portion of the aerospace industry
is in english units.  Altitude is in feet, velocity is in mph or fps, fuel
is in pounds, and engines are horsepower or pounds of thrust.  The only
major aeronautical sector that uses metric is (was?) the Soviets.

But, here's a handy way to remember how to do hp <==> W conversions:

     In fourteen hundred and ninety two,
     Columbus sailed the ocean blue;
     Divide the son of a bitch by two,
     and you get the number of Watts in a horsepower.

(For the mathematically or poetically disinclined, 1492/2 = 746
which is about how many Watts are in 1 horsepower, 745.7 is exact)

  However, the Swedish AF uses metrics even on the altimeters, while the civil
aviation uses feets and stuff.

  An interesting side-effect of this is that some of the SK-60 jet-trainers
that are cleared to land on civilian fields have two altimeters, one in meters
and one in feets....

  (A friend in the terminal room claims that Saab uses metrics in it's aviation
sector too, which I cannot confirm. I have however seen construction drawings
for a/c's built by Saab done in metrics..)
