How to convert calories to milliwatt-hours?

Sure! To convert calories (cal) to milliwatt-hours (mWh), you'll need to use the following conversion factor:

1 calorie (cal)≈0.00116222 watt-hours (Wh)1 \text{ calorie (cal)} \approx 0.00116222 \text{ watt-hours (Wh)}

Since 1 watt-hour is equal to 1000 milliwatt-hours:

1 Wh=1000 mWh1 \text{ Wh} = 1000 \text{ mWh}

Thus,

1 cal≈0.00116222 Wh×1000 mWh/Wh=1.16222 mWh1 \text{ cal} \approx 0.00116222 \text{ Wh} \times 1000 \text{ mWh/Wh} = 1.16222 \text{ mWh}

So, 1 calorie is approximately 1.16222 milliwatt-hours.

Real World Examples

  1. Food Energy:

    • A medium-sized apple has about 95 calories.
      • Energy Content: 95 calories×1.16222 mWh/cal≈110.4109 mWh95 \text{ calories} \times 1.16222 \text{ mWh/cal} \approx 110.4109 \text{ mWh}

  2. Burning Calories with Exercise:

    • Jogging for 30 minutes burns roughly 300 calories.
      • Energy Burned: 300 calories×1.16222 mWh/cal≈348.666 mWh300 \text{ calories} \times 1.16222 \text{ mWh/cal} \approx 348.666 \text{ mWh}

  3. Daily Caloric Intake:

    • The average daily caloric intake recommended for an adult is about 2000 calories.
      • Daily Intake Energy: 2000 calories×1.16222 mWh/cal≈2324.44 mWh2000 \text{ calories} \times 1.16222 \text{ mWh/cal} \approx 2324.44 \text{ mWh}

  4. Snacks:

    • One chocolate chip cookie typically contains around 50 calories.
      • Energy Content: 50 calories×1.16222 mWh/cal≈58.111 mWh50 \text{ calories} \times 1.16222 \text{ mWh/cal} \approx 58.111 \text{ mWh}

Conclusion

Calories can be converted into milliwatt-hours using the conversion factor, and by knowing this, you can compare the energy content of various foods and the amount of energy burned during different activities in terms of electrical energy units.

See below section for step by step unit conversion with formulas and explanations. Please refer to the table below for a list of all the Milliwatt-hours to other unit conversions.

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:

  1. 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.
  2. 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.
  3. 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 milliwatt-hours?

A Milliwatt-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 m, metric prefix, for 0.001 or 10−310^{-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 10−310^{-3} is representing Milli prefix in mWh unit.
