I decided to calculate the energy of cottage cheese. It’s a small meal I really like to eat for lunch at school.
100g of cottage cheese has 88kcal.
Calculation:
1 kcal = 0.001163 kWh
88 x 0.001163 = 0.102344 kWh
To calculate the result I used the numbers from this homepage.

We had the task to calculate the energy of a meal our choice, from kcal to kJ and kWh. Sunday is "brunch-day"! So i've chosen some delicious American-Style Pancakes: More...
I wanted to know, how I can convert kcal (kilocalories) or even kJ (kilojoules) to kWh (kilowatt-hours).
To calculate this, I created an Excel-file with the units of energy and below my calculations with two products, which I usually eat for breakfast.
