An ice cream has a marked value of $700 \,kcal$. How many kilowatt- hour of energy will it deliver to the body as it is digested ............ $kWh$
$1\,kcal = {10^3}\,Calorie = 4200\,J$$ = \frac{{4200}}{{3.6 \times {{10}^6}}}{K_w}h$
$700\,kcal = \frac{{700 \times 4200}}{{3.6 \times {{10}^6}}}kWh = 0.81\,kWh$
