## How to convert gigajoules to joules (GJ to J)

The formula for converting gigajoules to joules is: J = GJ × 1000000000. To calculate the gigajoule value in joules first substitute the gigajoule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 gigajoule in joules we follow these steps:

J = GJ × 1000000000

J = 1 × 1000000000

J = 1000000000

In other words, 1 gigajoule is equal to 1000000000 joules.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 gigajoules to joules is:

- Understand the conversion formula: J = GJ × 1000000000
- Substitute the required value. In this case we substitute 5 for GJ so the formula becomes: J = 5 × 1000000000
- Calculate the result using the provided values. In our example the result is: 5 × 1000000000 = 5e+9 J

In summary, 5 gigajoules is equal to 5e+9 joules.

## Converting joules to gigajoules

In order to convert the other way around i.e. joules to gigajoules, you would use the following formula: GJ = J × 0.000000001. To convert joules to gigajoules first substitute the joule value into the above formula, and then execute the calculation. If we wanted to calculate 1 joule in gigajoules we follow these steps:

GJ = J × 0.000000001

G1 = J × 0.000000001

GJ = 0.000000001

Or in other words, 1 joule is equal to 0.000000001 gigajoules.

## Conversion Unit Definitions

### What is a Gigajoule?

^{9}joules. The prefix "giga-" signifies a factor of one billion, so a gigajoule represents a very large amount of energy.

### What is a Joule?

^{2}/s

^{2}in terms of mass, length, and time.
