How to convert calories to ergs (cal to erg)

The formula for converting calories to ergs is: erg = cal × 41868000. To calculate the calorie value in ergs first substitute the calorie value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 calorie in ergs we follow these steps:

erg = cal × 41868000

erg = 1 × 41868000

erg = 41868000

In other words, 1 calorie is equal to 41868000 ergs.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 2 calories to ergs is:

  1. Understand the conversion formula: erg = cal × 41868000
  2. Substitute the required value. In this case we substitute 2 for cal so the formula becomes: erg = 2 × 41868000
  3. Calculate the result using the provided values. In our example the result is: 2 × 41868000 = 83736000 erg

In summary, 2 calories is equal to 83736000 ergs.

Converting ergs to calories

In order to convert the other way around i.e. ergs to calories, you would use the following formula: cal = erg × 0.00000002390057361. To convert ergs to calories first substitute the erg value into the above formula, and then execute the calculation. If we wanted to calculate 1 erg in calories we follow these steps:

cal = erg × 0.00000002390057361

cal = 1 × 0.00000002390057361

cal = 0.00000002390057361

Or in other words, 1 erg is equal to 0.00000002390057361 calories.

Conversion Unit Definitions

What is a Calorie?

A calorie (cal) is a unit of energy commonly used in nutrition. It represents the amount of energy required to raise the temperature of one gram of water by one degree Celsius (or one degree Kelvin). In the context of nutrition, the term "calorie" usually refers to a kilocalorie, which is equal to 1,000 calories in scientific terms.
The energy content of food and beverages is often measured in kilocalories, abbreviated as kcal or Cal (with an uppercase "C" to distinguish it from the smaller "cal" used in physics).
In scientific terms, 1 kilocalorie is equal to 4.184 kilojoules (kJ). The conversion factor between kilocalories (kcal) and kilojoules (kJ) is 1 kcal = 4.184 kJ.
In everyday language, when people refer to the number of calories in food, they are usually referring to kilocalories. For example, if a food label says a serving contains 200 calories, it means 200 kilocalories or 200,000 calories in scientific terms.

What is a Erg?

An erg is a unit of energy and mechanical work in the centimeter-gram-second (CGS) system of units. It is equal to the amount of work done by a force of one dyne applied over a distance of one centimeter. In other words, an erg is a very small unit of energy.
1 erg is equal to 1 × 10-7 joules in the International System of Units (SI).
The erg is rarely used in modern contexts, especially in comparison to larger energy units like joules or kilojoules. However, it is still employed in specific scientific disciplines, such as astrophysics and quantum mechanics, where very small energy values are often encountered.
Here are some examples of how much energy is in an erg:
  • The energy required to lift a mass of 1 gram a distance of 1 centimeter against gravity.
  • The energy of a 10-meter-per-second breeze blowing on a 1-square-centimeter surface area.
  • The energy of a single photon of red light.
