FAQ

What is the conversion factor from cal/K to kWh/K?
1 cal/K equals 1.162222e-6 kWh/K. To convert, multiply the value in calories per kelvin by 1.162222e-6.
How do I convert 1 cal/K to kWh/K?
1 cal/K = 1.16222e-6 kWh/K. For any value, multiply by 1.162222e-6.
How do I convert kWh/K back to cal/K?
Divide by the same factor — or equivalently, multiply by 860420.7. So 1 kWh/K = 860421 cal/K.
When would I need to convert calorie per kelvin to kilowatt-hour per kelvin?
Thermal-capacity conversions between cal/K and kWh/K appear in thermal-mass analysis of bodies, calorimetry, R-C thermal-network modelling, electronics thermal capacitance and large-equipment thermal-storage sizing. J/K and kJ/K are the SI standard; MJ/K and kWh/K cover large-equipment and building thermal-mass notation; BTU/°F is the US convention; cal/K and kcal/K are common in chemistry and thermochemistry. This category is lumped heat capacity only — it does NOT include specific heat capacity (J/(kg·K), requires mass), molar heat capacity (J/(mol·K), requires molecular weight) or volumetric heat capacity, all of which are different physical quantities.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
