Hand vs Hand percentage

Okay, I have been looking around and haven't found out how to do the math for hand vs hand preflop. IE:

Hero has AQs.
I put my opponent on KJs.

What is the percentage that I win the hand? Also, sorry if this was already posted before. I couldn't seem to find it. Thanks.

Not sure if it's exactly what you're looking for in regards to pre-flop but it explains everything postflop.
