Discover the ease of converting kilocalories to millijoules with our user-friendly kcal to mJ tool. Developed by Newtum, this page offers precise conversions that pique your curiosity and aid your calculations.
A kilocalorie (kcal) is a unit of energy commonly used in nutrition. It is defined as the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere. Kilocalories are also known as 'food calories' and are used to quantify the energy content in foods and beverages.
Definition of MillijouleA millijoule (mJ) is a unit of energy in the International System of Units (SI). It is equal to one-thousandth of a joule, the SI unit of energy. The millijoule is a small unit of energy that is often used in scientific and technical fields to measure the energy transferred, used, or stored in a particular process or reaction.
| Kilocalorie (kcal) | Millijoule (mJ) |
|---|---|
| 1 kcal | 4184 mJ |
| 2 kcal | 8368 mJ |
| 3 kcal | 12552 mJ |
| 4 kcal | 16736 mJ |
| 5 kcal | 20920 mJ |
| 6 kcal | 25104 mJ |
| 7 kcal | 29288 mJ |
| 8 kcal | 33472 mJ |
| 9 kcal | 37656 mJ |
| 10 kcal | 41840 mJ |
1 kcal = 4184 mJ
Example 1:
Convert 2 kcal to mJ:
2 kcal = 2 × 4184 mJ = 8368 mJ
Example 2:
Convert 5 kcal to mJ:
5 kcal = 5 × 4184 mJ = 20920 mJ
The Kilocalorie to Millijoule Converter is a tool that stems from the need to bridge different energy units. Historically, the kilocalorie was widely used in chemistry and physics, while the millijoule became important with the advent of the SI system, necessitating an accurate conversion mechanism.
Explore the practicality of the kcal to mJ converter and see how it brings clarity to energy-related calculations across various applications.
Example 1:
To convert 3 kcal to mJ, multiply by 4184:
3 kcal = 3 × 4184 mJ = 12552 mJ
Example 2:
To convert 7 kcal to mJ, multiply by 4184:
7 kcal = 7 × 4184 mJ = 29288 mJ
