How to convert kilocalories to kilowatt-hours?

Sure! To convert kilocalories (kcal) to kilowatt-hours (kWh), you need to use a conversion factor.

1 kilocalorie (kcal) = 0.00116222 kilowatt-hours (kWh)

Here is the formula for the conversion: $\text{kWh} = \text{kcal} \times 0.00116222$

So, to convert 1 kilocalorie to kilowatt-hours: $1 \text{kcal} \times 0.00116222 \text{kWh/kcal} = 0.00116222 \text{kWh}$

Here are some real-world examples to illustrate the energy contained in different quantities of kilocalories:

Example 1: A slice of bread

A typical slice of bread contains about 80 kcal. To convert this to kilowatt-hours: $80 \text{kcal} \times 0.00116222 \text{kWh/kcal} = 0.0929776 \text{kWh}$ This means that the energy content of one slice of bread is roughly 0.093 kilowatt-hours.

Example 2: A chocolate bar

A standard chocolate bar contains about 250 kcal. To convert this to kilowatt-hours: $250 \text{kcal} \times 0.00116222 \text{kWh/kcal} = 0.290555 \text{kWh}$ This equates to approximately 0.291 kilowatt-hours of energy.

Example 3: Daily caloric intake

An average daily caloric intake for an adult might be around 2000 kcal. To convert this to kilowatt-hours: $2000 \text{kcal} \times 0.00116222 \text{kWh/kcal} = 2.32444 \text{kWh}$ This means that the total daily energy intake for an average adult is about 2.324 kilowatt-hours.

Example 4: A marathon

Running a marathon typically burns up approximately 2600 kcal. To convert this to kilowatt-hours: $2600 \text{kcal} \times 0.00116222 \text{kWh/kcal} = 3.021772 \text{kWh}$ Therefore, the energy expended during a marathon is approximately 3.022 kilowatt-hours.

These examples help illustrate how kilocalories can be equated to a more universally understood unit of energy, like kilowatt-hours, which is commonly used to measure electrical energy.

What is kilocalories?

Kilocalories (kcal) are a unit of energy that measures the amount of heat or energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius. In other words, it's a measure of how much energy is needed to change the state of a substance (in this case, water).

In nutrition and food science, kilocalories are used to express the energy content of foods and drinks. One kilocalorie is equal to 1000 calories (not to be confused with "Calories" which is capitalized and refers to the unit of energy specifically related to the human body). The term "kilocalorie" is often shortened to simply "calorie", but technically, it's a measure of the energy content of foods and drinks.

Here are some examples of how kilocalories are used in everyday life:

Food labels: When checking nutrition labels on packaged foods, you'll see the energy content listed in kilocalories (kcal).
Caloric intake: The number of kilocalories an individual consumes or burns is a measure of their caloric balance.
Physical activity: The energy expended during exercise or physical activity is also measured in kilocalories.

To give you an idea of the scale, here are some approximate kilocalorie values for common foods and drinks:

Apple (1 medium): 95 kcal
Banana (1 medium): 105 kcal
Cup of coffee: 0-2 kcal
Glass of water: 0 kcal

I hope that helps you understand what kilocalories are!

What is kilowatt-hours?

A Kilowatt-hour is a unit of energy and its units, kWh, are formed with W for watt and h for hour from SI unit system combined with letter k, metric prefix, for 1,000 or $10^3$ . Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.

Followings equivalent equations are identical but in different units. Please note that factor $10^3$ is representing Kilo prefix in kWh unit.

1 kWh = 10^3*Pt = 10^3*IVt = 3600 * 10^3*J = 2.247 * 10^{22} * 10^3 eV = 8.598*10^5 * 10^3 cal

$P - Power$
$t - Time \text{ (in hours. Multiply by 3600 to convert to seconds)}$
$I - Current$ $V - Volts$
$J - Joules$
$eV - Electronvolt$
$cal - Calories$
