Convert kilocalorie (th) to kilojoule

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.

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.

How to Convert kilocalorie (th) to kilojoule

To convert kcal to kJ, you might employ the subsequent instructions:

Instructions for Transformation: kJ = kcal × 4.184

These instructions are established on the particular that 1 kilocalorie = 4.184 kilojoules. Step-by-Step kilocalories to kilojoules Transformation:

  • Pick the digit of kilocalories you enjoy to remake to kilojoules.
  • Operate the instructions: Reproduce the digit of kcal by 4.184 to convey the comparable weight in kilojoules.
  • Illustration: 100 kilocalories and must remake them to kj: Kilojoules = 100 kcal × 4.184 ≈ 418.4 kJ

So, 100 kilocalories are roughly 418.4 kilojoules. This technique lets you transform power elements from kilocalorie to kilojoule without online assistance.

To convert kilocalorie (th) to kilojoule, the formula is used,
kJ = kcal(th) × 4.184
where the kcal (th) to kJ value is substituted to get the answer from Energy Converter.

How many kilocalorie (th) in a kilojoule

A kJ is about 0.239 kcal. In other words, 1 kilojoule is roughly 0.239 kilocalories. So, 1000 kilojoules are approximately equal to 239 kilocalories. Kcal to kj are both elements of power, but kilojoules are the more miniature element.
