As homework we had to choose a meal and calculate how much energy is in it.
So I chose something I eat several times a week.
This is what I calculated:
203.32 kcal --> 853.70 kJ --> 0.237138889 kWh
I calculated with the following link: from kcal/ kJ to kWh (umrechnung.org)

Hi there
As Homework we had to calculate the kj to kwh from a meal.
Every morning I eat a cup of cereals. So I decided to take a cup of cereals as an example.
So 100 g of Kelloggs Cornflakes has about 372 kcal.
Calculation:
1 kcal = 4.1868 kJ = 0.001163 kWh
372 kcal = 1557.50 kJ = 0.432636 kWh
For the calculation I used the following link: calculation kJ and kWh

Our 4th task was to calculate the energy of a food with these three units of measurement: kilocalories (kcal), kilojoules (kJ) and kilowatt-hours (kWh). One of my favourite food is pizza so I choose that for my calculation: More...
Hello everybody!
I want to show you an example how to calculate a portion spaghetti bolognese from kcal to KJ and from kcal to kWh:
Here the calculation:
kcal to KJ
0.239 kcal : 1 KJ x 171 kcal = 715.481 KJ
kcal to kWh
0.00116 kWh : 1 kcal x 171 kcal = 0.19874 kWh

So now, have fun with calculating your example! :)

Here is my example, how to calculate kcal to kWh and kJ, on an everyday Food.
1 portion rice witch vegetables:

calculation:
313 kcal * 4.19 kJ = 1311.47 kJ
313 kcal / 860 kcal = 0.363953488 kWh
For the calculations i used the following link:
Energieeinheiten (agrarplus.at)

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.

How do I convert Kcal or kJ to kWh?
For the conversion of the different energy units the following table could be helpful:

For both prototypes:
1. Where is the draft saved? Have the rights to save the draft local on our Computer.
2. It's not so creative. Create the app more interessting for example with a nice design.
3. More precise Questions.
Prototype 1 (long):
1. The map isn't working well.

Team: Selina, Lisa, David, Shana
Version 1: Zu kompliziert, Zu aufwändig, Viele Informationen sind überflüssig (Bsp. Sprachmemo), unübersichtlich, könnte spannender und organisierter gestaltet sein
Version 2: Könnte ebenfalls interessanter und organisierter gestaltet sein, es ist ziemlich monoton, Es wäre von Vorteil, wenn man ein Datum erfassen könnte, Bessere Gliederung, Detailliertere Fragen
Improvements:
Prototype 1
The Question „Where did you buy it?“ is not completly clear. From where do you have to take the information of the height and the precision. Our group think that this question is not necessary!
We don‘t understand why we have to upload a voice comment. Why is it important?
Prototype 2
The voice comment is also in this version not necessary.
Conclusion:
Our opinion is that the short version is much better than version 1. It‘s easier to understand and it goes faster to register a new product.
