For our homework we had the task to calculate energy from kJ to kWh.
Since a few years I am very interested in sports but also nutrition. For me it is very important to keep myself fit and nourish my body with the food that it needs.
Therefore, I’ve decided to calculate the energy which I burn during my workout and the food that I eat afterwards.
On Monday evening I went to my CrossFit lesson which’s load time was 30 minutes - total endurance 1 hour. My Garmin watch counted a total consumption of 320 calories during the workout.
Afterwards, I ate broccoli, spatzli and smoked tofu for dinner. The dish had a total calories of 380.
To calculate the calories of my food I use the app myfitnesspal and to convert the calories to KJ and kWh I’ve used this website.
I burned:
320 kilo calories (kcal) - which is 1339.776 kilojoules (kJ) - which is 0.37216 kilowatthours (kWh)
I ate:
380 kilo calories kcal - which is 1590.984 kilojoules (kJ) - which is 0.44194 kilowatthours (kWh)
I’ve decided to make the comparison of food burned and food eaten because I think it’s very interesting to see, how much energy we need during a workout in relation to the food that we eat.
