# Convert kilojoule to kilocalorie (th)

## What is a kilojoule?

A kJ or kilojoule corresponds to 1000 or 103 joules. This metric is common in nutrition and dietology and is utilized to describe how much energy we get from different products. It is also common for the description of reactions in chemistry. In this case, kJ/mol or kilojoules per mole describe the energy that is transformed in them.

Altogether, kJ as well as kilocalories are mainly used to establish the energetic value of a compound or reaction. The prefix kilo in these metrics means that the units of measurement go with a factor of 103. Thus, the number must be multiplied by 1000 to get the corresponding amount in joules.

The basic definition tells us that joules describe the work done by a 1-newton force, which moves mass for 1 meter in the force’s direction. As for the kilojoules, they have the same meaning only multiplied by 103.

## What is a kilocalorie?

A kilocalorie is a derivative of calories. To understand its meaning we should first state that a calorie equals the amount of energy that makes one gram of water warmer by 1°C at standard pressure. The term has a Latin origin and the word calor initially meant heat.

Furthermore, the energetic value of food is usually measured in larger units such as kilocalories. One kcal corresponds to 1000 calories. The latter has several estimations in joules. For instance, international cal equals 4.1868 J and thermochemical or th one corresponds to 4.1840 J. Therefore, kcal (th) will have the meaning of 4184.0 J.

It should be noted that dietology and other related areas often omit the prefix kilo- and utilize a calorie with a meaning that corresponds to a kilocalorie. This happens due to historical reasons, since earlier the terms small and large calories were officially used.

## How to Convert kilojoule to kilocalorie

To convert kj to kcal, you might employ the next instructions and forms: Instructions for transformation: Kcal = KJ / 4.184. These instructions are founded on the variety that 1 kilocalorie = 4.184 kilojoules.

Step-by-Step Transformation:

• Choose the digit of KJ you want to correct to Kcal.
• Operate the instructions: Separate the numeral of kilojoules by 4.184 to obtain the comparable importance in kilocalories.

Illustration: 1000 KJ and desire to transform it to kilocalories: Kilocalories = 1000 kJ / 4.184 ≈ 239.005 kcal

So, 1000 kilojoules is approximately equal to 239.005 Kcal. This process authorizes the correct power elements from kj in kcal without requiring kj to kcal converter.

To convert kilojoule to kilocalorie (th) , the formula is used,
$\mathrm{kcal}=\mathrm{kJ}×0.239006$
where the kJ to kcal (th) value is substituted to get the answer from Energy Converter.
1 kJ
=
0.239 kcal (th)
1 kcal (th)
=
4.184 kJ
Example: convert 15 kJ to kcal (th):
15 kJ
=
15
x
0.239 kcal (th)
=
3.5851 kcal (th)

## How many kilojoules in a kilocalorie

A kilocalorie, frequently anointed a calorie in simple terminology, is analogous to 4.184 kilojoules. This indicates that 1 kcal is = 4.184 kj. For the model, finishing a meal item with 100 kilocalories provides roughly 418.4 kilojoules of power. Kj to kcal are both elements of power, but they counter in their numerical importance, with kilojoules being the more undersized element.
