It uses a scrypt algorithm, not SHA-256
Oh, so they're equivalent? OK!
Scrypt is roughly a similar number in KH as SHA256 is in MH. ROUGHLY. Some people, for a numbers example, can get 1000 MH in SHA256, and get 1200 KH in Scrypt, through tuning of parameters (that's just a number example to get across the concept, not an actual factual number.) For ease in thinking about things, though, you can think that a card that runs 1000 MH mining a SHA256 coin is roughly capable of 1000 KH mining a Scrypt coin.
As to if Scrypt is the same, equivalent, to SHA256... No. The two are totally different engines.
