A Kilocalorie, often simply called a calorie, is a unit of energy. It is defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius. This unit is commonly used in nutrition to express the energy content of foods and is equivalent to 1,000 small calories (cal).
Definition of AttojouleAn Attojoule is an extremely small unit of energy in the metric system. It is equal to one quintillionth of a Joule (1 aJ = 10^-18 Joules). Due to its minute size, the Attojoule is commonly used in scientific contexts to measure tiny amounts of energy, such as those observed at the quantum level.
| Kilocalorie (IT) (kcal) | Attojoule (aJ) |
|---|---|
| 1 kcal | 4.184 x 10^21 aJ |
| 2 kcal | 8.368 x 10^21 aJ |
| 3 kcal | 12.552 x 10^21 aJ |
| 4 kcal | 16.736 x 10^21 aJ |
| 5 kcal | 20.920 x 10^21 aJ |
| 6 kcal | 25.104 x 10^21 aJ |
| 7 kcal | 29.288 x 10^21 aJ |
| 8 kcal | 33.472 x 10^21 aJ |
| 9 kcal | 37.656 x 10^21 aJ |
| 10 kcal | 41.840 x 10^21 aJ |
1 kcal = 4.184 x 10^21 aJ
Example 1:
convert 2 kcal to aJ:
2 kcal = 2 x 4.184 x 10^21 aJ = 8.368 x 10^21 aJ
Example 2:
convert 5 kcal to aJ:
5 kcal = 5 x 4.184 x 10^21 aJ = 20.920 x 10^21 aJ
The concept of converting Kilocalories to Attojoules stems from the need to reconcile different energy measurement systems. This conversion facilitates scientific communication and precision in fields ranging from nutrition to physics, where understanding and quantifying energy at varying scales is essential.
Understanding the real-life applications of Kilocalorie to Attojoule conversions can unveil the relevance of energy measurement in various scientific domains.
Example 1:
Convert 0.5 kcal to aJ:
0.5 kcal = 0.5 x 4.184 x 10^21 aJ = 2.092 x 10^21 aJ
Example 2:
Convert 10 kcal to aJ:
10 kcal = 10 x 4.184 x 10^21 aJ = 41.840 x 10^21 aJ
