Discover the ease of converting energy units from Gigajoules to Kilocalories with our intuitive GJ to kcal converter, crafted by Newtum to enhance your calculations.
A Gigajoule (GJ) is a unit of energy within the International System of Units (SI) equivalent to one billion (1,000,000,000) joules. A joule is the energy expended when a force of one newton is applied over a displacement of one meter. In practical terms, gigajoules measure substantial quantities of energy, often used in scientific and industrial applications to represent large-scale energy consumption or production.
Definition of KilocalorieA Kilocalorie (kcal), also known as the food calorie, is a unit of energy defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere. It is commonly used in nutrition to quantify the energy content in food, with one kilocalorie being equivalent to approximately 4.184 kilojoules, the standard unit of energy in the International System of Units (SI).
| Gigajoule (GJ) | Kilocalorie (kcal) |
|---|---|
| 0.01 GJ | 2388.46 kcal |
| 0.1 GJ | 23884.6 kcal |
| 0.5 GJ | 119423 kcal |
| 1 GJ | 238846 kcal |
| 2 GJ | 477692 kcal |
| 5 GJ | 1194230 kcal |
| 10 GJ | 2388460 kcal |
| 20 GJ | 4776920 kcal |
| 50 GJ | 11942300 kcal |
| 100 GJ | 23884600 kcal |
1 GJ = 238,846 kcal
1 kcal = 0.000004184 GJ
Example 1:
Convert 2 GJ to kcal:
2 GJ = 2 × 238,846 kcal = 477,692 kcal
Example 2:
Convert 0.5 GJ to kcal:
0.5 GJ = 0.5 × 238,846 kcal = 119,423 kcal
