Hello everyone
In Task 4 it's our excercise to calculate an everyday example of food from kcal/kJ to kWh.
Here is my result for a portion spaghetti with tomatosauce:

For the calculation I used the conversion factors from the following homepage:
And now I show you, how I calculated the kWh and kJ exactly:
kcal to kJ
325 * 4.1868 = 1360.71
kcal to kWh
325 * 0.001163 = 0.377975
Have fun with calculating your food into your energy!
best wishes,
