HRM and machines at gym

Options
Hi I was just curious...I have a polar ft7 and it links in with the exercise machines in the gym. The heart rate is the same on both but I end up burning more calories on the HRM than what the machine says.....Is this right?

    Mine is the opposite. I have a polar FT40. Ran 2 miles on the treadmill the other day and my HRM said I only burned 230 calories while the treadmill said 330. Maybe it is somewhere in between?
