How to convert calories to gigawatt-hours?

To convert calories to gigawatt-hours, you need to understand the relationship between these units of energy.

1 calorie (cal) is defined as approximately 4.184 joules (J).

1 gigawatt-hour (GWh) is defined as $10^9$ watt-hours (Wh). And since 1 watt-hour is 3600 joules (J) (because 1 hour = 3600 seconds, and 1 watt = 1 joule/second), we can calculate:

1 GWh = $10^9 \text{ Wh} \times 3600 \text{ J/Wh} = 3.6 \times 10^{12} \text{ J}$ .

Now, to convert from calories to gigawatt-hours:

1 cal = 4.184 J,

so to get joules into gigawatt-hours, you need to set up the conversion factor:

1 GWh = $3.6 \times 10^{12} \text{ J}$ ,

Thus,

$\text{1 calorie} = 4.184 \text{ J} \times \left( \frac{1 \text{ GWh}}{3.6 \times 10^{12} \text{ J}}\right)=1.1622 \times 10^{-12} \text{ GWh}$

So, 1 calorie is approximately $1.162 \times 10^{-12} \text{ GWh}$ .

Real-World Examples for Other Quantities of Calories

Daily Human Consumption:
- The average daily caloric intake for an adult is about 2000 to 2500 calories. This can be converted to gigawatt-hours as follows: $2500 \text{ cal} \times 1.162 \times 10^{-12} \text{ GWh/cal} \approx 2.905 \times 10^{-9} \text{ GWh}$
Chocolate Bar:
- A typical chocolate bar has about 250 calories. $250 \text{ cal} \times 1.162 \times 10^{-12} \text{ GWh/cal} \approx 2.905 \times 10^{-10} \text{ GWh}$
Marathon Run:
- Running a marathon burns approximately 2600 calories. $2600 \text{ cal} \times 1.162 \times 10^{-12} \text{ GWh/cal} \approx 3.0212 \times 10^{-9} \text{ GWh}$
Fuel:
- 1 gallon of gasoline contains approximately 31,000,000 calories. $31,000,000 \text{ cal} \times 1.162 \times 10^{-12} \text{ GWh/cal} \approx 3.6002 \times 10^{-5} \text{ GWh}$

These conversions demonstrate how small the energy values in calories are when converted to gigawatt-hours, a measure often used in larger-scale energy contexts like electrical grid output.

What is calories?

Calories are a unit of measurement that represents the amount of energy your body gets from consuming food and drinks. In other words, they measure the energy content of what you eat.

Here's how it works:

Your body uses calories to function: To grow, repair tissues, and maintain basic bodily functions (like beating your heart or breathing), your body needs a certain amount of energy.
Food provides that energy: When you eat food, the carbohydrates, proteins, and fats in those foods are broken down into different forms of energy. This process is called metabolism.
Calories represent that energy: The total amount of energy from these processes is measured in calories (or kilocalories). One calorie is equal to 4.184 joules.

Think of it like this:

A car engine needs gasoline to run, and a certain amount of gasoline provides a specific amount of energy.
Similarly, your body "runs" on the energy provided by the foods you eat. The more calories in those foods, the more energy they provide for your bodily functions.

Here are some common examples of calorie sources:

1 banana: approximately 100-110 calories
1 apple: around 95 calories
1 cup of cooked rice: about 200-250 calories

When you consume a certain amount of calories, your body uses that energy to perform various functions. Excess calories can lead to weight gain if not balanced with physical activity or burned off through exercise.

Does this help clarify what calories are?

What is gigawatt-hours?

A Gigawatt-hour is a unit of energy and its units, GWh, are formed with W for watt and h for hour from SI unit system combined with letter G, metric prefix, for 1,000,000,000 or $10^9$ . 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 $10^9$ is representing Giga prefix in GWh unit.

1 GWh = 10^9*Pt = 10^9*IVt = 3600 * 10^9*J = 2.247 * 10^{22} * 10^9 eV = 8.598*10^5 * 10^9 cal

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