Kilocalorie to Gigajoule Conversion Formula

To convert from Kilocalorie (kcal) to Gigajoule (GJ), use the following formula:

 Gigajoule (GJ)\textbf{ Gigajoule} \text{ (GJ)}

=1000×4.184×1109× Kilocalorie (kcal)= 1000 \times 4.184 \times \frac{1}{10^{9}}\times \textbf{ Kilocalorie} \text{ (kcal)}

=1106×4.184× Kilocalorie (kcal)= \frac{1}{10^{6}} \times 4.184\times \textbf{ Kilocalorie} \text{ (kcal)}

=0.000004184× Kilocalorie (kcal)= 0.000004184\times \textbf{ Kilocalorie} \text{ (kcal)}

With 4.1844.184 is the ratio between the base units Joule (J) and calorie (cal).

Example

Let's convert 5 Kilocalorie (kcal) to Gigajoule (GJ).

Using the formula:

5×0.000004184=0.000020925 \times 0.000004184 = 0.00002092

Therefore, 5 Kilocalorie (kcal) is equal to 0.000020920.00002092 Gigajoule (GJ).

What is a Kilocalorie (kcal)?

A Kilocalorie (kcal) is a unit of energy, equal to one thousand calories (1000 cal). The plural form is Kilocalories.

What is a Gigajoule (GJ)?

A Gigajoule (GJ) is a unit of energy in the International System of Units (SI), equal to one billion Joules (109 J). The plural form is Gigajoules.

What is the International System of Units (SI)?

The International System of Units (SI) is the modern form of the metric system and the most widely used system of measurement in the world. It is founded on seven fundamental units: the second (time), meter (length), kilogram (mass), ampere (electric current), kelvin (thermodynamic temperature), mole (amount of substance), and candela (luminous intensity).
