A rough rule of thumb is that a 150 pound person burns about 100 calories per mile walked. So 90 calories for 1.8 km @ 132 pounds sounds about right.
Of course, using the incline on the treadmill can significantly increase the calorie burn at a given speed. About 50% more for 5% incline, and double for 10% incline for a given speed.
Also, I am wondering whether you are mixing up your units of measurement - you report your weight in pounds, but distance in km. And 3.6 kmh does seem kinda slow for walking.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
