lbs thrust to english horsepower

[bazathome]

I have been doing some reading on the new Airbus A380 that has Rolls Royce or Pratt and Whitney Engines, that produce 70,000 lbs of thrust at take off, X 4 engines thats a fair amount of power and i expect a large amount of fuel consumed.
Can someone convert this to horsepower for me as i can relate to the value of horsepower better.
Also what would be the fuel consumption be.
The only aircraft engine fuel consumption figure's that i can work out is a naturally asperated engine of 80-400 hp is 0.27 litres /hp/hour or 0.42 lbs/hp/hour.
Anyone interested in the new Airbus A380 just search the term A380 or go to http://news.bbc.co.uk/2/hi/business/4183201.stm

Power is force times velocity. One horsepower is 550 foot-pounds per second.

So at 550 feet per second (375mph), each pound of thrust is one horsepower. At 825 feet per second (560mph), each pound of thrust is 1.5 horsepower.

But what about the parts in between?
