Estimate calories burned at a different weight?

I have been doing a kettlebell exercise video, and the website for it says that this workout burns 8-12 calories per minute for a 130 pound woman. Is there a formula I can use to figure out what the burn would be for me at 152 pounds? I know it wouldn't be completely accurate, but I don't have a HRM, so I'd like to at least get a rough estimate.
