Converting from Gigajoule (GJ) to Gigacalorie (Gcal) | Energy

What is Gigajoule (GJ)

A Gigajoule (GJ) is a unit of energy in the International System of Units (SI). It is equivalent to one billion joules, where a joule is the standard unit of energy. Gigajoules are commonly used in scientific and industrial applications to measure large amounts of energy.

What is Gigacalorie (Gcal)

A Gigacalorie (Gcal) is a unit of energy commonly used in the field of nutrition to measure the energy content of food. It is equivalent to one billion calories, where a calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.

Conversion Formulas

To convert from Gigajoule (GJ) to Gigacalorie (Gcal) or vice versa, you can use the following formulas:

Gcal=GJ×0.2388459

GJ=Gcal×4.1868

Examples

1. Converting 6 Gigajoules (GJ) to Gigacalories (Gcal):

6GJ=6×0.2388459=1.433075Gcal

2. Converting 15 Gigajoules (GJ) to Gigacalories (Gcal):

15GJ=15×0.2388459=3.582688Gcal

3. Converting 9 Gigacalories (Gcal) to Gigajoules (GJ):

9Gcal=9×4.1868=37.6812GJ
