Heart rate monitor calories burned vs other

I have a garmin chest strap that I use with a Garmin monitor and other Garmin sensors on my bike to track cadence, speed and heart rate. The Garmin website gives on reading for calories used and the Strava website shows a very different number. The generic number on MFP is very high compared to these two.

Anyone know of a way to estimate calories burned so I know which of these is correct. Garmin seems to be the more accurate one. Example: 30 min on the bike avg 16.4 mph with an avg heart rate of 160 bpm (yes I'm out of shape and I have a high max hr of 203), Garmin shows 463 cals burned and Strava shows 217. Any way to confirm one of these is accurate?

    I tend to trust my Garmin (I'm using the HRM & cadence sensor too) it comes in far lower than many other calculators I've seen (including MFP) but I suspect to really get an accurate number you'd need to know how many watts you were putting out and that can get a little pricey!

    The Garmin is about half of whats in MFP but Strava records it at about half of what Garmin does. I'm just curious why. Thanks for the input! I have been using the Garmin numbers and will continue to unless someone can explain why its wrong.

    Thanks again.

    What are you using the number for, exactly?

    I put it in MFP as the calories I have burned for that exercise. I'm just trying to have the most accurate data available.

    I've had several HRMs including Polar and the one that came with my Timex Global trainer. I always trusted them more than the machines, usually because I've put my stats in the watches I wear with the chest strap. I think using the same source of data all the time is going to be more consistent, and therefore better.

    After a few weeks, your actual vs expected weight loss will tell you how accurate your burn numbers are (assuming the food logging is accurate!)
