FAQ

What is the conversion factor from BTU/°F to kWh/K?
1 BTU/°F equals 0.0005275279 kWh/K. To convert, multiply the value in British thermal units per degree Fahrenheit by 0.0005275279.
How do I convert 1 BTU/°F to kWh/K?
1 BTU/°F = 0.000527528 kWh/K. For any value, multiply by 0.0005275279.
How do I convert kWh/K back to BTU/°F?
Divide by the same factor — or equivalently, multiply by 1895.634. So 1 kWh/K = 1895.63 BTU/°F.
When would I need to convert British thermal unit per degree Fahrenheit to kilowatt-hour per kelvin?
Thermal-capacity conversions between BTU/°F 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).
