calorie to Gigajoule Conversion Formula

To convert from calorie (cal) to Gigajoule (GJ), use the following formula:

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

=4.184×1109× calorie (cal)= 4.184 \times \frac{1}{10^{9}}\times \textbf{ calorie } (cal)

=4.184×10−9× calorie (cal)= 4.184\times 10^{-9}\times \textbf{ calorie } (cal)

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

Example

Let's convert 5 calorie (cal) to Gigajoule (GJ).

Using the formula:

5×4.184×10−9=2.092×10−85 \times 4.184\times 10^{-9} = 2.092\times 10^{-8}

Therefore, 5 calorie (cal) is equal to 2.092×10−82.092\times 10^{-8} Gigajoule (GJ).
