Discover the ease of converting calories (cal) to millijoules (mJ) with our Calorie th to Millijoule Converter, brought to you by Newtum. Let's make unit conversion simple and precise!
A Calorie, specifically a 'thermochemical calorie' (cal), is a unit of energy. It is defined as the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere. It is a small energy unit, often used in chemistry and biology to measure energy values in foods and reactions.
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, which is the SI unit for energy. A joule is the amount of energy transferred when a force of one newton is applied over a distance of one meter. Thus, a millijoule is a measure of energy that is used for smaller scales and is very common in physics and engineering applications.
| Calorie (cal) | Millijoule (mJ) |
|---|---|
| 1 cal | 4.184 mJ |
| 5 cal | 20.92 mJ |
| 10 cal | 41.84 mJ |
| 20 cal | 83.68 mJ |
| 50 cal | 209.2 mJ |
| 100 cal | 418.4 mJ |
| 200 cal | 836.8 mJ |
| 500 cal | 2092 mJ |
| 1000 cal | 4184 mJ |
| 5000 cal | 20920 mJ |
1 cal = 4.184 mJ
1 mJ = 0.239005736 cal
Example 1:
Convert 10 cal to mJ:
10 cal = 10 × 4.184 mJ = 41.84 mJ
Example 2:
Convert 25 cal to mJ:
25 cal = 25 × 4.184 mJ = 104.6 mJ
The concept of converting calories to millijoules stems from the need to align with the International System of Units (SI). Historically, the calorie was used in various scientific contexts, but the adoption of the joule as the SI unit of energy necessitated the development of conversion tools like the Calorie th to Millijoule Converter to maintain consistency and precision in energy measurements.
Understanding the practical uses of the Calorie th to Millijoule Converter can provide valuable insights into energy management and nutritional science.
Example 1:
If you have 15 calories (cal) and want to convert it to millijoules (mJ), you multiply by the conversion factor:
15 cal × 4.184 mJ/cal = 62.76 mJ
Example 2:
To convert 75 calories (cal) to millijoules (mJ):
75 cal × 4.184 mJ/cal = 313.8 mJ
Q1: What is the conversion factor from calories to millijoules?
A1: The conversion factor is 1 cal = 4.184 mJ.
Q2: How accurate is the Calorie th to Millijoule Converter?
A2: The converter is highly accurate, utilizing the standard conversion factor recognized in scientific measurements.
