Have an HRM but doesn't calculate calorie burn, anyone have

I have an HRM, but it doesn't calculate calories burned. It does have the chest strap and watch. I bought it years ago when I was pregnant to monitor my heart rate when exercising. Does anyone have a formula I can use so I can use my HRM while working out and then calculate my calorie burn? I didn't google this yet, hoping someone has it handy
Thanks

I've heard this is pretty accurate and it is what I use since I have the same type of HRM http://www.braydenwm.com/calburn.htm

It is ok if you are doing something with a steady heart rate, could get tricky if you are doing intervals

Thanks. I am doing P90X right now and wanted to try and figure out my calorie burn.
