Factor1 cal/(cm²·s·°C) = 41840 W/(m²·K)

Converter

cal/(cm²·s·°C)

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

Result
41840W/(m²·K)

Rendered to 6 significant figures.

Formula

Formula
W/(m²·K) = cal/(cm²·s·°C) × 41840

Multiply any value in calories per square centimetre-second-Celsius by 41840 to obtain the value in watts per square metre-kelvin.

Worked example

Convert 1 cal/(cm²·s·°C) to W/(m²·K).

  1. 01Start with 1 cal/(cm²·s·°C).
  2. 02Multiply by the conversion factor: 1 × 41840 = 41840 W/(m²·K).
Result1 cal/(cm²·s·°C) = 41840 W/(m²·K)

FAQ

What is the conversion factor from cal/(cm²·s·°C) to W/(m²·K)?
1 cal/(cm²·s·°C) equals 41840 W/(m²·K). To convert, multiply the value in calories per square centimetre-second-Celsius by 41840.
How do I convert 1 cal/(cm²·s·°C) to W/(m²·K)?
1 cal/(cm²·s·°C) = 41840 W/(m²·K). For any value, multiply by 41840.
How do I convert W/(m²·K) back to cal/(cm²·s·°C)?
Divide by the same factor — or equivalently, multiply by 2.390057e-5. So 1 W/(m²·K) = 2.39006e-5 cal/(cm²·s·°C).
When would I need to convert calorie per square centimetre-second-Celsius to watt per square metre-kelvin?
Heat-transfer coefficient conversions between cal/(cm²·s·°C) and W/(m²·K) are needed in heat-exchanger sizing, boiler and condenser design, and HVAC calculations. W/(m²·K) is standard in SI engineering, and BTU/(hr·ft²·°F) is common in US heat-exchanger correlations and vendor literature.
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).
