# 'walking' calories estimate seems very wrong

I believe that a 180lb person burns 100 cal per mile (speed doesn't matter much), and the calories are proportional to one's weight.

I'm 194lb and just logged 65 minutes of walking at 3.0mph. This should have been

194/180 * 65/60 * 3 * 100 = 350 cal, but I'm only seeing 229. Why?

So lets say you are a big person who burns 100 calories an hour even if you don't move. That would be 2400 calories in total. This person might burn 150 calories per hour of walking. But 100 of those would have been burned either way. So cronometer would say they only burned 50 calories from walking. I think that's why.

Hi @maxb ,

We calculate the energy burned from exercise based on the adjusted MET values given from the Compendium of Physical Activities (https://sites.google.com/site/compendiumofphysicalactivities/).
