Sweat vs Calorie Burn?

Why do some exercises make you sweat more but burn less calories overall?

I was sweating a ton riding the stationary bike (and lifting weights at the same time) but I don't sweat a lot on the elliptical. The elliptical burns way more calories than the bike. So why does the bike make me sweat more?

    What are you using to get your calorie reads from?

    Its heart rate based.

    I can sweat going on a 4.0mph walk on a spring day but it burns like 120cals for a 2mi walk.

    And I've done 4mi runs without sweating much but since my heart rates higher, its more calories.

    And HRMs arent accurate for lifting. Just mostly accurate for steady state cardio

    Sweat is not an indicator of caloric burn.

    Are you actually sweating more on the bike or do you just notice it more due to the relative lack of upper body motion on a stationary bike? Perception or reality?

    Right ... sweat is not an indicator of caloric burn.

    I can wear an extra layer of clothing when I cycle, and sweat more, but I'm not burning additional calories.

    If you're using more muscles or working them harder you will sweat more. Not necessarily cardio. I tend to sweat more during strength exercises than cardio.

    All other things being equal, possibly. But it's still not an indicator of energy expenditure, it's an indicator of body temperature.
