**TI-84 Plus CE: Calories Burned While Walking**

**Introduction**

*Caution: These programs give an estimate on the number of total calories burned. Other factors such as the intensity of the walk may be needed to taken into consideration. This blog entry should not be considered professional medical advice.*

There
are two programs that estimate the number of calories burned during a single
walking session. WALKCAL uses your
stride and the number of steps as inputs.
If your stride isn’t known, an average stride is estimated based on your
height. WALKDIST uses distance traveled
and time it took to travel such distance as input. WALKDIST is the more simple program of the
two.

All
units are entered in U.S. units. Since
the formulas use SI units, some conversions are necessary. The programs will perform all necessary
conversions upon execution.

**WALKCAL**

WALKCAL: Calories burned by inputting your stride (in
feet), weight (in pounds), number of steps walked, and the time of the walk (in
hours).
