# Convert kilojoule to joule

## 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 joule?

Joule is a metric that is utilized for the evaluation of work, heat and energetic levels and has international recognition. Its definition tells us that it corresponds to the work done by a 1-newton force, which moves mass for 1 meter in the force’s direction. Therefore, one J equals one N per m or one kg x m² x s-².

It is also applied in electrical area and means the work of the force of an electric field done for 1 second at a 1-volt voltage to keep the stability of a 1-ampere current.

The term was introduced at the Second International Congress of Electricians, held in the year of Joule's death and was recognized internationally nine years after this event. From that time, one international joule equals 1.00020 absolute units. Later, this unit was also applied as the standard and belongs to the metrics applicable worldwide.

## How to Convert kilojoules to joules

Convert kj to j is an uncomplicated methodology that concerns changing the height ranking by an aspect of 1000. Here's how you might accomplish it:

• Decide the digit of J you desire to transform into kcal.
• Simply multiply the numeral of kilojoules by 1,000: accept the matching matter in joules.

Illustration: 3,000 kJ × 1,000 = 3,000,000 J. So, 3,000 kilojoules is equal to 3,000,000 joules. This technique delivers an effortless method to correct significance elements kilojoules to joules without requiring online benefits.

To convert kilojoule to joule, the formula is used,
$J=\mathrm{KJ}×1000$
where the kJ to J value is substituted to get the answer from Energy Converter.

## How many joule in a kilojoule

The distinction among kj to joules lies in the hierarchy of height. J- the more miniature element generally employed in scientific and engineering contexts. At the same time, kilojoules are a more extensive element, frequently used to represent more significant quantities of power in daily situations.

Illustration: 5 kJ × 1,000 = 5,000 J. So, to correct from kj to j, multiply by 1000, making it more straightforward to operate with less power.
