A kilocalorie, abbreviated as kcal, is a unit of energy. It is commonly used in nutrition to indicate the amount of energy that food provides when consumed. One kilocalorie equals the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius. This unit is essential in dietary energy measurement.
Definition of kilojouleA kilojoule (kJ) is a unit of energy in the International System of Units (SI). It measures the work needed to exert a force of one thousand newtons over a distance of one meter. Kilojoules are widely used in various fields, including physics, engineering, and nutrition, to quantify energy content and expenditure.
| Kilocalorie (kcal) | Kilojoule (kJ) |
|---|---|
| 1 kcal | 4.184 kJ |
| 5 kcal | 20.92 kJ |
| 10 kcal | 41.84 kJ |
| 20 kcal | 83.68 kJ |
| 50 kcal | 209.2 kJ |
| 100 kcal | 418.4 kJ |
| 150 kcal | 627.6 kJ |
| 200 kcal | 836.8 kJ |
| 250 kcal | 1046 kJ |
| 500 kcal | 2092 kJ |
1 kcal = 4.184 kJ
1 kJ = 0.239 kcal
Example 1:
convert 5 kcal to kJ:
5 kcal = 5 × 4.184 kJ = 20.92 kJ
Example 2:
convert 10 kcal to kJ:
10 kcal = 10 × 4.184 kJ = 41.84 kJ
The kilocalorie to kilojoule conversion has its roots in the adoption of the metric system and the need for a consistent energy measurement. It has become crucial in nutrition and science, where energy content and conversion from food intake to energy expenditure are essential.
Explore the practical applications of converting kcal to kJ and how it can benefit your daily life.
Example 1:
Converting 50 kcal to kJ:
50 kcal = 50 × 4.184 kJ = 209.2 kJ
Example 2:
Converting 120 kcal to kJ:
120 kcal = 120 × 4.184 kJ = 502.08 kJ
