What is a Specific Heat Capacity Converter?
A specific heat capacity converter is a tool that converts specific heat capacity values between different unit systems. Specific heat capacity measures the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree, and is fundamental in thermodynamics, chemistry, and engineering.
How to Convert Specific Heat Capacity Units
Select the source and target specific heat capacity units from the dropdown menus. Enter the value and the converter instantly calculates the equivalent. Note that cal/(g·°C), kcal/(kg·°C), Btu/(lb·°F), and CHU/(lb·°C) are all numerically equal.
Specific Heat Capacity Conversion Formulas
History of Specific Heat Capacity Measurement
The concept of specific heat was developed by Joseph Black in the 18th century. The calorie was originally defined as the heat needed to raise 1 gram of water by 1°C, making water's specific heat exactly 1 cal/(g·°C). With SI adoption, the joule became the standard energy unit, giving water a specific heat of 4186.8 J/(kg·K).
About This Specific Heat Capacity Converter
This specific heat capacity converter supports 9 units including J/(kg·K), J/(kg·°C), J/(g·°C), kJ/(kg·K), cal/(g·°C), kcal/(kg·°C), Btu(IT)/(lb·°F), Btu(th)/(lb·°R), and CHU/(lb·°C). Several of these are numerically equivalent due to unit relationships.
Frequently Asked Questions
What is specific heat capacity?
Specific heat capacity is the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree. Water has a high specific heat (4186.8 J/(kg·K)), meaning it takes a lot of energy to heat up.
Is J/(kg·K) the same as J/(kg·°C)?
Yes, since the Kelvin and Celsius scales have the same degree size, J/(kg·K) and J/(kg·°C) are numerically identical for specific heat capacity.
Why are cal/(g·°C) and Btu/(lb·°F) equal?
Both units were historically defined relative to water: 1 calorie heats 1 gram of water by 1°C, and 1 Btu heats 1 pound of water by 1°F. The mass and temperature ratios cancel out, making them numerically equal.
What is the specific heat of water?
Water has a specific heat of 4186.8 J/(kg·K), or equivalently 1 cal/(g·°C) or 1 Btu/(lb·°F). This is one of the highest specific heats of any common substance.
How is specific heat capacity used in engineering?
Engineers use specific heat to calculate heating/cooling loads, design heat exchangers, determine thermal energy storage capacity, and predict temperature changes in materials during manufacturing processes.
