How do I know how many calories I burned?

3Daughtersin2015

If I know my heart rate during a work out how do I translate that to calories burned to log into myfitnesspal? For example I rode my bike for 20 minutes and my heart rate was at 184 average. Thanks

Shapesense.com has calculators for that! I prefer to use those than MFP's totals. I calculate the net calories not the gross calories.
