What is Calorie per Gram-°C?
The calorie per gram-°C (cal/g·°C) is a unit of specific heat capacity commonly used in chemistry and physics. It represents the amount of heat energy (in calories) required to raise the temperature of one gram of a substance by one degree Celsius. This unit is particularly useful in calorimetry experiments and for understanding the thermal properties of materials.
One calorie per gram-°C is equivalent to 4184 joules per kilogram-kelvin (J/kg·K), which is the SI unit for specific heat capacity. Our specific heat capacity conversion tool helps you easily convert between calorie per gram-°C and other units. For example, water has a specific heat capacity of approximately 1 cal/g·°C or 4184 J/kg·K.
What is the SI Unit for Specific Heat Capacity?
The SI unit for specific heat capacity is joule per kilogram-kelvin (J/kg·K). It represents the amount of heat energy (in joules) required to raise the temperature of one kilogram of a substance by one kelvin. Our specific heat capacity conversion tool helps convert between this SI unit and other units like calorie per gram-°C:
- 1 cal/g·°C = 4184 J/kg·K
What is Calorie per Gram-°C Used For?
Calorie per gram-°C is used in various scientific and engineering applications, particularly in fields dealing with thermal properties of materials:
Chemistry
Determining the heat capacity of chemical substances in calorimetry experiments. For example, measuring the specific heat of a metal to identify its composition.
Physics
Understanding thermal properties of materials in thermodynamics studies. For instance, calculating the energy needed to heat a substance in a physics lab.
Food Science
Analyzing the thermal properties of food materials during processing and storage. For example, determining heating requirements for food manufacturing.

Etymology and History
The calorie was originally defined as the amount of heat required to raise the temperature of 1 gram of water by 1°C at standard atmospheric pressure. The "gram calorie" (cal) became widely used in chemistry and physics, giving rise to the specific heat capacity unit cal/g·°C.
With the adoption of the SI system, the joule became the preferred unit for energy, leading to the use of joule per kilogram-kelvin (J/kg·K) as the standard unit for specific heat capacity. However, calorie per gram-°C remains in common use, particularly in educational contexts and certain specialized applications. The conversion factor between these units (1 cal/g·°C = 4184 J/kg·K) reflects the relationship between the calorie and joule energy units.
Frequently Asked Questions
What is specific heat capacity?
Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree. For calorie per gram-°C, it represents the calories needed to heat one gram of material by one Celsius degree. This property is essential for understanding how materials respond to thermal energy in various scientific and engineering applications.
How do I convert calorie per gram-°C to joules per kilogram-kelvin?
To convert from calorie per gram-°C to joule per kilogram-kelvin, multiply by 4184. This conversion factor accounts for both the energy unit change (calorie to joule) and mass unit change (gram to kilogram). For example, 1 cal/g·°C = 4184 J/kg·K. Our specific heat capacity converter tool handles this calculation automatically.
Why is water's specific heat capacity 1 cal/g·°C?
Water's specific heat capacity is defined as 1 cal/g·°C because the calorie was originally defined based on water's thermal properties. Specifically, one calorie was defined as the energy needed to raise the temperature of 1 gram of water by 1°C. This definition makes water's specific heat capacity exactly 1 in these units, which is why it serves as a reference point in many thermal calculations.
What materials have high specific heat capacities?
Materials with high specific heat capacities include water (1 cal/g·°C), hydrogen gas (3.4 cal/g·°C), and ammonia (1.15 cal/g·°C). These substances require significant energy to increase their temperature, making them useful for thermal regulation applications. Metals generally have lower specific heat capacities, such as aluminum (0.215 cal/g·°C) and copper (0.092 cal/g·°C).
How is specific heat capacity measured?
Specific heat capacity is typically measured using calorimetry, where a known amount of heat is added to a known mass of material, and the resulting temperature change is measured. The formula c = Q/(mΔT) is used, where c is specific heat capacity, Q is heat added, m is mass, and ΔT is temperature change. Our calorie per gram-°C converter helps translate between different unit representations of these measurements.
What's the difference between specific heat and heat capacity?
Heat capacity is the total amount of heat required to raise the temperature of an entire object by one degree, while specific heat capacity is the heat required per unit mass. Specific heat capacity (like cal/g·°C) is an intensive property that doesn't depend on the amount of material, whereas heat capacity is an extensive property that increases with sample size.
Why is specific heat capacity important in engineering?
In engineering, specific heat capacity is crucial for designing heating and cooling systems, thermal management in electronics, and material selection for various applications. For example, knowing that water has a high specific heat capacity (1 cal/g·°C) explains why it's used as a coolant in car radiators and industrial processes. Engineers use these values to calculate energy requirements and system performance.
