Kilowatts are a measure of power.
Power is how fast we can do the work, i.e. I could move 10 tonnes of rock!! but it would take me a long time... ergo, I am less powerful than a truck which could move 10 tonnes in much less time.
So, in short:
1 horsepower is 550lbft/sec [i.e. the power to lift 550lb by 1 foot, each second]
From here: www.pumaracing.co.uk/power1.htm
1 HP = 0.7457 KW / 1KW = 1.341 BHP
(or in other words a 100HP engine is producing 74.57Kw of power, or a 100KW engine is producing 134BHP).

Anyone know how to calculate a power figure in KW from either BHP or ft/lb torque?
bhp to kW is straightforward - multiply your bhp figure by 0.7457. Remember that PS/CV/PK as used in mainland Europe is a slightly different figure than imperial bhp.
Working from lbft, you can only get a figure for that specific RPM. This is almost certainly not what you're looking for, I suspect.

Indeed: the torque (lbft) rating of a car doesn't have an "easy" correlation between that and power (either horsepower or KW, which are basically different units for the same thing). Maximum torque is usually not produced at the same rev-point as maximum horsepower either.
