The erg is a unit of energy in the centimeter-gram-second (CGS) system of units. It is defined as the amount of work done when a force of one dyne is applied over a distance of one centimeter. The erg is a small unit of energy, often used in physics and engineering contexts, particularly in fields dealing with small-scale energy measurements.
In the realm of energy measurement, the erg is standardized within the CGS system. To provide context, 1 erg is equivalent to 10^-7 joules in the International System of Units (SI). This standardization allows for easy conversions between different energy units, making it a valuable tool for scientists and engineers alike.
The erg was first introduced in the late 19th century as scientists sought a more manageable unit for measuring small quantities of energy. Over time, as the field of physics evolved, the erg became a staple in various scientific disciplines, particularly in thermodynamics and electromagnetism. Despite the rise of the joule as the more commonly used unit of energy, the erg remains relevant in specific applications.
To illustrate the use of the erg, consider a scenario where a force of 2 dynes is applied over a distance of 3 centimeters. The work done can be calculated as follows:
[ \text{Work (in ergs)} = \text{Force (in dynes)} \times \text{Distance (in cm)} ]
[ \text{Work} = 2 , \text{dynes} \times 3 , \text{cm} = 6 , \text{ergs} ]
The erg is primarily used in scientific research and academic settings where precise measurements of small energy quantities are necessary. It is particularly useful in fields such as physics, chemistry, and engineering, where energy conversions and calculations are commonplace.

The thermochemical calorie, denoted as "th cal," is a unit of energy defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere. This unit is particularly significant in the fields of chemistry and thermodynamics, where it is used to quantify energy changes in chemical reactions.
The thermochemical calorie is standardized based on the specific heat capacity of water. It is essential to note that there are different types of calories, such as the dietary calorie (Cal) and the mechanical calorie (cal), which may have different values. The thermochemical calorie is specifically used in scientific contexts, ensuring consistency and accuracy in energy measurements.
The concept of the calorie dates back to the 19th century when scientists began to explore the relationship between heat and energy. The thermochemical calorie emerged as a crucial unit in thermodynamics, allowing researchers to quantify energy changes during chemical reactions. Over the years, advancements in technology and scientific understanding have led to the refinement of calorie definitions, but the thermochemical calorie remains a vital tool in energy calculations.
To illustrate the use of the thermochemical calorie, consider a simple example: If 10 grams of water is heated from 20°C to 30°C, the energy required can be calculated using the formula:
[ \text{Energy (th cal)} = \text{mass (g)} \times \text{temperature change (°C)} ]
In this case: [ \text{Energy} = 10 , \text{g} \times (30 - 20) , \text{°C} = 10 , \text{g} \times 10 , \text{°C} = 100 , \text{th cal} ]
The thermochemical calorie is widely used in various scientific applications, including:
