A person uses 1800 {\rm kcal} to run for 2.4 {\rm h}. Convert the energy for running to the following energy units: how many calories
To convert 1800 kcal to calories, we need to understand the relationship between these two units.
1 kilocalorie (kcal) is equal to 1000 calories.
So, to convert from kcal to calories, we multiply the value by 1000.
Let's use this conversion formula to find the answer:
1800 kcal * 1000 calories/kcal = 1,800,000 calories
Therefore, 1800 kcal is equal to 1,800,000 calories.
