## What Is a Kilocalorie?

A kilocalorie is a unit used to measure energy.

Kilocalories can be abbreviated as kcal; for example, 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.

### Uses

The large calorie is most often used to measure the energy content in foods. This is used to measure the energy stored in foods that is used by the body to perform work.

## How Much Is a Kilocalorie?

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

## How to Convert Kilocalories

To convert kilocalories to another unit of energy, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for kilocalories in the conversion table below.

Then, multiply the energy measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

kilocalories × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
