Can't remember how to do this lol

I can't remember how I figured this out before. ....lol. But I want to know how you figure out how many calories you burn during a cardio workout. I found something on the internet a few weeks back that showed how to do it but I can't find it now. And now that I've lost a few lbs I think I might have to go back and redo it so that it will be right. Does anyone know how to do that ?. (besides Math was never my strong subject anyway. LOL.) Thanks for the help !.

I'm not sure there is a way to know *exactly*, but most heart rate monitors can give you a good estimation as they take your heart rate, age, sex, weight and height into account.
