Hello guys I also have a question. Why Bitcoin Hash rates are written as 1000MH/s and Litecoins as 1000KH/s.
these number are written for the same card i.e if we take example of 6990 the has rates for BTC and LTC are written as.

BTC 900MH/s
LTC 900KH/s

What is the difference between them?
I doubt that they are not written correctly. Both should be KH/s
