Swimming

I don't have a heart rate monitor and I'm going to go for a swim, I'll do laps and I'll do it for about 30 minutes. Does anyone know roughly how many calories that would burn and/or a good tool I could use to get the amount?

(I'm 5ft9 and weigh 185lbs.)

I just use what MFP calculates for swimming when I select it from their list of exercises. It seems just as reasonable as anything else I've ready anyplace else.
