Discover the ease of converting energy from kilocalories to megajoules with our precise 'kcal to MJ' tool, crafted by the experts at Newtum.
A kilocalorie, commonly abbreviated as kcal, is a unit of energy. It is defined as the amount of heat energy needed to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere. The kilocalorie is widely used in nutrition to quantify the energy content in foods and is commonly called a 'calorie' in dietary contexts.
Definition of MegajouleA megajoule (MJ) is a unit of energy in the International System of Units (SI). It is equal to one million joules. The joule is the SI unit for energy, defined as the work done when a force of one newton displaces an object by one meter. Therefore, a megajoule represents a significant amount of energy, often used in industrial and scientific applications to measure large quantities of energy.
| Kilocalorie (kcal) | Megajoule (MJ) |
|---|---|
| 1 kcal | 0.004184 MJ |
| 10 kcal | 0.04184 MJ |
| 50 kcal | 0.2092 MJ |
| 100 kcal | 0.4184 MJ |
| 200 kcal | 0.8368 MJ |
| 500 kcal | 2.092 MJ |
| 1000 kcal | 4.184 MJ |
| 5000 kcal | 20.92 MJ |
| 10000 kcal | 41.84 MJ |
| 50000 kcal | 209.2 MJ |
1 kcal = 0.004184 MJ
1 MJ = 238.8458966275 kcal
Example 1:
convert 100 kcal to MJ:
100 kcal = 100 × 0.004184 MJ = 0.4184 MJ
Example 2:
convert 250 kcal to MJ:
250 kcal = 250 × 0.004184 MJ = 1.046 MJ
The Kilocalorie to Megajoule converter is a tool that has evolved with the advancement of nutritional science and energy measurement. Its history is tied to the development of units for energy and the need for conversions between them for various practical applications. The converter simplifies the process of translating the energy content of food, represented in kilocalories, into megajoules, a unit preferred in scientific and engineering contexts.
Explore practical uses of the 'kcal to MJ' converter and unveil its significance in various real-life scenarios.
Example 1:
Convert 300 kcal to MJ:
300 kcal = 300 × 0.004184 MJ = 1.2552 MJ
Example 2:
Convert 750 kcal to MJ:
750 kcal = 750 × 0.004184 MJ = 3.138 MJ
