Calories burned have been way under!

Just found this website with a calculator to determine calories burned per heart rate:

http://www.livestrong.com/article/314866-how-many-calories-are-burned-if-heart-rate-is-130-for-60-minutes/

It takes into account your age, weight, and heartrate.
Lately, I've been getting into 180-190HR during my 35 minute cardio sessions. MFP logs this as about 300 calories burned. This equation brought me to about 800 cals burned.
Who do I believe? Underestimating is always better, I suppose. But does anyone know exact measurements on heart rate and how it correlates to calories burned?
I don't have a HRM (heart rate monitor), so bear with me. I am aware that is the best indicator.

    Get a heart rate monitor that will calculate calories burned. The tools that guess don't give you a real estimate. MFP is high for some things, VERY low on others. Only really accurate solution is to get a heart rate monitor. I've got a Polar one with a chest strap and it's great. VERY accurate and allows you to adjust by weight and age and all. Great tool. Can't be sure without one.

    What was your AVERAGE heart rate? It seems like this is what's used to calculate. This is another site I've used.

    We just bought HRMs this week, and I love that it takes so much of the guesswork out.

    300 sounds more realistic. I burn 200 according to my HRM for a 30 minute interval elliptical session.

    I wanted to avoid the cost factor of a HRM, but it looks like that's my only option! :P Haha thanks everyone :flowerforyou:

    I have been looking for a good monitor that is accurate. What type is yours, where can I get it, and how much? Thanks!

    HRM is the only way to be sure. I say invest in one...its a worthwhile investment

    I don't know your age or physical condition, but the first thing I would question is whether you are truly sustaining a heart rate of 180-190 throughout your 35 minute cardio session. That's very high, and if you look at the heart rate charts, you'd have to be very young, and at about 90-98% of your max heart rate to sustain those levels. If you're 20, for instance, your max heart rate would be approximately 200 - 20, or 180. Then you'd want to exercise at some percentage of that maximum, depending on your goals.
    No one exercises at their maximum heart rate for very long, that's for sure.

    Right, I was using the HRM on the machine, and this was after doing a 5 resistance on a stationary bike for 25 minutes at 13MPH, I moved onto the treadmill and was tracking my HR on its handlebar HRM. So, I know it was high, I was drenched, but I'd rather be sure it's that high. I remember being younger and watching out, I get into anaerobic exercise quite often and don't realize it.
