A Calorie is a unit of energy that is widely used in nutrition to quantify the amount of energy that food provides. It is essentially the amount of energy required to raise the temperature of one gram of water by one degree Celsius, under specified conditions. In the context of dietary energy, calories (often spelled with a capital C) are actually kilocalories. This means that when we say a food item has 200 calories, it actually contains 200,000 calories in scientific terms. Calorie measurement plays a crucial role in diet planning, weight management, and understanding the energy balance of foods.
Definition of KilojouleA Kilojoule is a unit of energy in the International System of Units (SI). It is equivalent to 1,000 joules, and it measures the amount of energy required to exert a force of one newton over a distance of one meter. In the context of food energy, kilojoules are often used as an alternative to calories. Understanding kilojoules is essential in fields like nutrition, physics, and engineering, as it helps quantify the energy content in food and energy expenditure. The conversion between calories and kilojoules is a common task in global nutrition labeling.
| Calorie (th)/hour | Kilojoule/hour |
|---|---|
| 1 cal/h | 4.184 kJ/h |
| 10 cal/h | 41.84 kJ/h |
| 50 cal/h | 209.2 kJ/h |
| 100 cal/h | 418.4 kJ/h |
| 200 cal/h | 836.8 kJ/h |
| 500 cal/h | 2092 kJ/h |
| 1000 cal/h | 4184 kJ/h |
| 5000 cal/h | 20920 kJ/h |
| 10000 cal/h | 41840 kJ/h |
| 20000 cal/h | 83680 kJ/h |
1 cal/h = 4.184 kJ/h
Example 1:
convert 50 cal/h to kJ/h:
50 cal/h = 50 × 4.184 kJ/h = 209.2 kJ/h
Example 2:
convert 200 cal/h to kJ/h:
200 cal/h = 200 × 4.184 kJ/h = 836.8 kJ/h
The Calorie (th)/hour to Kilojoule/hour Converter has roots in the need for standardized energy measurements. Initially, calories were the popular unit in many regions, especially in nutrition. However, with globalization and the rise of the metric system, kilojoules became more prevalent, particularly in scientific fields. This shift necessitated precise and reliable conversion tools to bridge the gap between the two units, ensuring accuracy in energy assessments across various domains.
The Calorie (th)/hour to Kilojoule/hour Converter is a valuable tool in various real-world scenarios, where accurate energy measurement and conversion are crucial.
