How to convert kilocalories to kilowatt hours (kcal to kWh)

The formula for converting kilocalories to kilowatt hours is: kWh = kcal × 0.0011622222. To calculate the kilocalorie value in kilowatt hours first substitute the kilocalorie value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 kilocalorie in kilowatt hours we follow these steps:

kWh = kcal × 0.0011622222

kWh = 1 × 0.0011622222

kWh = 0.0011622222

In other words, 1 kilocalorie is equal to 0.0011622222 kilowatt hours.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 9 kilocalories to kilowatt hours is:

  1. Understand the conversion formula: kWh = kcal × 0.0011622222
  2. Substitute the required value. In this case we substitute 9 for kcal so the formula becomes: kWh = 9 × 0.0011622222
  3. Calculate the result using the provided values. In our example the result is: 9 × 0.0011622222 = 0.0104599998 kWh

In summary, 9 kilocalories is equal to 0.0104599998 kilowatt hours.

Converting kilowatt hours to kilocalories

In order to convert the other way around i.e. kilowatt hours to kilocalories, you would use the following formula: kcal = kWh × 859.84522785899. To convert kilowatt hours to kilocalories first substitute the kilowatt hour value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilowatt hour in kilocalories we follow these steps:

kcal = kWh × 859.84522785899

kcal = 1 × 859.84522785899

kcal = 859.84522785899

Or in other words, 1 kilowatt hour is equal to 859.84522785899 kilocalories.

Conversion Unit Definitions

What is a Kilocalorie?

A kilocalorie (kcal), commonly referred to as a Calorie with an uppercase "C," is a unit of energy used in the field of nutrition and dietary measurement. It represents the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius. In scientific terms, 1 kilocalorie is equal to 1,000 calories (lowercase "c"), which are the smaller units used in physics.
In the context of nutrition, the energy content of food and beverages is often measured in kilocalories. For example, if a food item contains 100 kilocalories, it means consuming that food provides the body with 100,000 calories of energy. Kilocalories are widely used on food labels and dietary recommendations to indicate the energy content of various foods and drinks.

What is a Kilowatt Hour?

A kilowatt-hour (kWh) is a unit of energy commonly used for measuring electricity consumption. It represents one kilowatt (kW) of power used continuously for one hour. In other words, it is a measure of energy equivalent to 1,000 watt-hours or 3.6 million joules.
Mathematically, 1 kilowatt-hour is equal to: 1 kWh = 1 kilowatt × 1 hour = 1,000 watts × 1 hour.
Kilowatt-hours are the standard billing units used by electric utilities for measuring the amount of energy consumed by residential, commercial, and industrial customers over time. For example, if you use a 1,000-watt (or 1 kilowatt) appliance for one hour, you will have consumed 1 kilowatt-hour of electricity. Utility bills often display the total energy consumption in kilowatt-hours, and consumers are charged based on the number of kilowatt-hours they use.
