Formula

Formula
cal/(cm·s·°C) = W/(cm·K) × 0.2390057

Multiply any value in watts per centimetre-kelvin by 0.2390057 to obtain the value in calories per centimetre-second-Celsius.

Worked example

Convert 100 W/(cm·K) to cal/(cm·s·°C).

  1. 01Start with 100 W/(cm·K).
  2. 02Multiply by the conversion factor: 100 × 0.2390057 = 23.9006 cal/(cm·s·°C).
Result100 W/(cm·K) = 23.9006 cal/(cm·s·°C)

FAQ

What is the conversion factor from W/(cm·K) to cal/(cm·s·°C)?
1 W/(cm·K) equals 0.2390057 cal/(cm·s·°C). To convert, multiply the value in watts per centimetre-kelvin by 0.2390057.
How do I convert 1 W/(cm·K) to cal/(cm·s·°C)?
1 W/(cm·K) = 0.239006 cal/(cm·s·°C). For any value, multiply by 0.2390057.
How do I convert cal/(cm·s·°C) back to W/(cm·K)?
Divide by the same factor — or equivalently, multiply by 4.184. So 1 cal/(cm·s·°C) = 4.184 W/(cm·K).
When would I need to convert watt per centimetre-kelvin to calorie per centimetre-second-Celsius?
Thermal conductivity conversions between W/(cm·K) and cal/(cm·s·°C) are common in insulation specification, heat-exchanger design, and building-envelope analysis. SI units (W/(m·K)) appear in international standards and simulation tools, while BTU/(hr·ft·°F) is standard in US codes and vendor datasheets.
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).
