cal/Ktokcal/K

Convert calories per kelvin (cal/K) to kilocalories per kelvin (kcal/K).

Factor1 cal/K = 0.001 kcal/K

Converter

cal/K

Accepts numbers or expressions, e.g. 150 + 14.7

Result
0.001kcal/K

Rendered to 6 significant figures.

Formula

Formula
kcal/K = cal/K × 0.001

Multiply any value in calories per kelvin by 0.001 to obtain the value in kilocalories per kelvin.

Worked example

Convert 1 cal/K to kcal/K.

  1. 01Start with 1 cal/K.
  2. 02Multiply by the conversion factor: 1 × 0.001 = 0.001 kcal/K.
Result1 cal/K = 0.001 kcal/K

FAQ

What is the conversion factor from cal/K to kcal/K?
1 cal/K equals 0.001 kcal/K. To convert, multiply the value in calories per kelvin by 0.001.
How do I convert 1 cal/K to kcal/K?
1 cal/K = 0.001 kcal/K. For any value, multiply by 0.001.
How do I convert kcal/K back to cal/K?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kcal/K = 1000 cal/K.
When would I need to convert calorie per kelvin to kilocalorie per kelvin?
Thermal-capacity conversions between cal/K and kcal/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).
