Hi Bonnie,

Stevia is so concentrated that it's hard to tell the equivelancy, it's like 1 Tsp (or 10 drops) for a cup of Splenda, but each manufacturer may extract differently to dilute it. I prefer liquid as I can measure the drops. Not sure about the carb count, but must be very low.

I've baked with it and love it. But many can't get used to it's taste.

Here are a few stevia links:
