Splenda and other artificial sweeteners are "hundreds" or "thousands" of times sweeter. How do they measure this? They taste the same to me.

Artificial sweeteners like Splenda are said to be hundreds or thousands of times sweeter than real sugar.  How do they measure this? And why is it that a teaspoon of splenda in one of those little packets tastes exactly as sweet as a teaspoon of sugar?  Shouldn't my mind be absolutely blown by how sweet it is?

Because it's also diluted thousands of times so that in the  packet it's about a 1:1 analog of sugar. 

That way when you are used to putting one packet of sugar in your coffee, you use one packet of Splenda. Otherwise your mind would be blown. Plus, it's hard to put only a couple of grains of Splenda in your coffee.
