## How to Convert Kilocalories to Joules

To convert a measurement in kilocalories to a measurement in joules, multiply the energy by the following conversion ratio: 4,184 joules/kilocalorie.

Since one kilocalorie is equal to 4,184 joules, you can use this simple formula to convert:

joules = kilocalories × 4,184

The energy in joules is equal to the energy in kilocalories multiplied by 4,184.

**For example,**here's how to convert 5 kilocalories to joules using the formula above.

### How Many Joules Are in a Kilocalorie?

There are **4,184** joules in a kilocalorie, which is why we use this value in the formula above.

1 kcal = 4,184 J

Kilocalories and joules are both units used to measure energy. Keep reading to learn more about each unit of measure.

## What 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.

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.

## What Is a Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.^{[1]} One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*; for example, 1 joule can be written as 1 J.
