New Pedometer Q.

I got a pedometer today. I've never used one, but so far I'm liking it. My question is, the calorie burning mode.....should I log those? I wasn't sure how accurate these are in that respect. Not like say, a heart monitor. It did allow me to calibrate the pedometer with my height, weight and stride length. I just wasn't sure if I should count this number as "calories burned" in my log?
