Not sure how many of you realized this before, but:
f(x) = x * (1-c) + 2x * c
f(x) = x * (1 + c)
f(x) = Total DPS
x = Base DPS
In other words, 1% crit chance results in a 1% net DPS increase. A 30% crit chance will result in a 30% damage increase. Note that this property does not scale additively. If you're at a 50% crit chance already, an additional 30% will only result in a ~20% damage increase.
If you want to fit an Infinity Edge and Lethality into the equation, the formula changes slightly.
f(x) = (1-c)x + 2.6cx
f(x) = (1.6c + 1)x
A 1% crit chance now results in a 1.6% net damage boost. In other words, the 20% crit chance on Infinity Edge results in a 40% overall damage boost, not counting the attack damage.

So basically: (%crit dmg - 100) * crit chance/100 = increased damage in % relative to your AD
I think that's a better way of putting it.
*Edited the formula, I misplaced the parenthesis >.>
