Just do what I do -- plug it in and then see if the car starts or not? (By the way, mine started today w/ two 45 second pre-glows at +3F today. And some of you said my block heater was not working!
I don't quite agree with the folks who just want to listen to the gurgle. If it is around freezing, then the block heater might be able to do that. I've heard it myself. My own experience (with a working block heater) is that if the temps are really low, zero or even lower, the block heater is working hard to keep up with the ambient temps, and you don't get the gurgle. 700 watts of heat will behave differently at 35F and -10F. It will still throw off heat but has a bit more of a challenge at staying ahead of the cold curve.
