What is the unit of luminious intensity?
candela--------------------------------------------The official international definition of candela (1979) is:"The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10e12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian".

Can you convert lumen to candle power?
Not directly, as you are comparing apples with oranges in two senses: (a) a lumen is an SI unit, whereas a candlepower is an Imperial unit, and (b) lumens are used to measure luminous flux, whereas candlepower is used to measure luminous intensity.
