Gigajoule to Kilojoule Conversion Formula

To convert from Gigajoule (GJ) to Kilojoule (kJ), use the following formula:

 Kilojoule (kJ)\textbf{ Kilojoule} \text{ (kJ)}

=109×11000× Gigajoule (GJ)= 10^{9} \times \frac{1}{1000}\times \textbf{ Gigajoule} \text{ (GJ)}

=106× Gigajoule (GJ)= 10^{6}\times \textbf{ Gigajoule} \text{ (GJ)}

Example

Let's convert 5 Gigajoule (GJ) to Kilojoule (kJ).

Using the formula:

5×106=50000005 \times 10^{6} = 5000000

Therefore, 5 Gigajoule (GJ) is equal to 50000005000000 Kilojoule (kJ).

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 a Kilojoule (kJ)?

A Kilojoule (kJ) is a unit of energy in the International System of Units (SI), equal to one thousand Joules (1000 J). The plural form is Kilojoules.

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).
